Primary 5 Calculation Questions, Primary 5 Calculation Questions and Answers

The size of the house is square meters, so it is not enough.

1: Cycling: 15 km);

2: Walking hours: 5 km).

A: You can walk an hour to the school. Cycling per hour, walking 4 kilometers; So don't be a kid to get to school.

The first problem is an application problem to find the area. square meters, square meters, 117 100, so not enough.

In the second question, distance is equal to time multiplied by speed. The home is more than 5,4km away from the school, so hours can reach the school.

Please, o( o thank you.

1。Not enough, the room area is about 8 * 5 = 40 square meters, the actual area is greater than the estimated area, the area of a square floor tile is square meters, a hundred pieces of a total of 36 square meters, so it is not enough. km, walk five kilometers per hour, hour is 5* kilometers, 4 >, so be able to walk.

According to about 71, 71 is less than 100 yuan, and the answer is enough.

Less than, A, Yes.

I don't know if it's right or not, please be satisfied.

.1 block), block) 8 * 13 = 104 (block) 104 100 is not enough (to meet the length of each side, can not exceed the length of the side,, I have also done this kind of problem,,)

25*15= Yes.

Thank you.

In the fifth grade, all of them are off-line calculation questions: 1) 25%*132+1 4*8 2)32*

are multiples of all, which can be converted separately and then extracted.
