The third grade students selected the fruits that everyone liked to eat, and how many people partici

Why don't you think this is an elementary school student?

There are 13 people who like to eat both fruits.

Problem solving process: (1) 50-42 = 8 people (to get the number of people who are determined to eat only pears) (2) 50-21 = 29 people (to get the number of people who are determined to eat only watermelon) (3) 8 + 29 = 37 people (to determine the sum of the number of people who eat only watermelon and the number of people who are determined to eat only pears) (4) 50-37 = 13 people (the total number of people who subtract the number of people who eat only one fruit, the total number of people who can eat two fruits must be the number of people who can eat two fruits).

42 plus 21 equals 63, and 63 minus 50 equals 13 people. So there are 13 people who like to eat both fruits.

I've seen your question, and I'm sorting out the answer, it will take about three minutes, please wait a while If my answer is helpful to you, please give it a thumbs up, thank you

42 + 21 = 63, 63-50 = 13 (people), so both fruits like to eat, there are 13 people.

Pay attention to the careful calculation, I hope it can help you.

Hello dear, if you think mine is helpful to you, can you move your fingers hard and give a like? It's really important to me, thank you. If you still want to consult different questions, it is recommended that you can click on the homepage to consult alone, thank you

This question requires a condition, each person must like a fruit.

Summary. Hello, there are 13 people in total

Calculation process: 9 + 8-4 = 17 - 4 = 13

There are nine students in the first class of the third grade who like to eat apples, and eight people who like to eat oranges, and four people who like to eat both kinds of oranges.

Hello There are a total of 13 people Calculation process: 9 + 8-4 = 17-4 = 13 People who like to eat apples and oranges include people who like both of them, if you add up the people who like to eat apples and those who like to eat oranges separately, then there will be a group of people who like apples and oranges at the same time, so the number of people who like apples and oranges at the same time is the final answer

Hope mine can help you <>

There's a loophole in this question, right? Who knows if there are any duplicates? If the same person likes to eat watermelon, apples and bananas, that's another problem......

Of course, looking at this volume, it is estimated that it is from elementary school, and it is not so complicated, so it all adds up directly:

25 + 17 + 15 + 6 + 23 + 25 + 18 + 9 = 138 But there are so many people in one class, it is unbelievable ......

What grade question is this?? If it's a question from elementary school, just add it up, and if it's a question from high school or college, you also have to consider students who like multiple fruits at the same time, so you need to classify it.

There are a total of 56 students in Class 31, each of whom likes to eat at least one kind of fruit, 41 people like to eat apples, 32 people like to eat pears, and how many people like to eat both kinds of fruits?

Hello, glad to answer for you. There are 17 people who like to eat both fruits, (41 + 32) - 56 = 73 - 56 = 17 (people).

There are a total of 50 students in a class, and each student likes to eat at least one kind of fruit, 42 people like to eat watermelon, 21 people like to eat pears like Sun Huan, and 13 people like to eat both fruits.

The calculation process is as follows:

There are 13 people who like to eat both fruits.

Subtraction calculations:If you choose any one of the numbers to subtract this number, you can add it with the rest of the numbers. For example:

Subtract several numbers from a number in a row, you can first add all the subtractions, and then subtract the sum of the subtractions from the subtracted numbers. For example: 276-115-85=276-(115+85)=76.

Summary. There are a total of 38 students, and if you add the people who like strawberries and bananas, and then subtract the total number of people, you will be able to find the number of people who like both types.

There are a total of 38 classmates, 32 like strawberries, 28 like bananas, each of them likes at least one fruit, how many people like both Wu Kaizheng?
