Sevenths translated, one out of seven 4 out of 7 7 7 7 out of 7?

The fraction is expressed as: cardinal number word (numerator) + ordinal word (denominator) Note: when the numerator is one, the ordinal word is singular; And when the numerator is greater than one, the denominator is plural.

So one in seven is: one seventh

If two out of seven it is: two seventhsok!

One seventh, very simply, in English, to mean fractions, the first word is a cardinal word, and the second word is an ordinal number. Cardinal words are like one, and ordinal words are like first, it's very simple. Come on Ro--b

Equal to one-seventh multiplied by seven-fourths multiplied by eight-sevenths equals two-sevenths.

1 in 7 4 out of 7 7 7 7 out of 8?

1/7/4/7/7/8=1/7x7/4x8/7=1/4x8/7=2/7

1 in 7 4 out of 7 7 7 7 out of 8?

Dividing by a number is equal to multiplying by the reciprocal of this number, and this equation is multiplication and division, without parentheses, so it only needs to be calculated in order, in multiplication, the numerator and denominator of different fractions can be reduced, one seventh 4/7 7 7/7.

1/7x7/4x8/7=2/7

Divide by a number, and the trapped Jiming is equal to multiplying it by its inverted number.

Analysis: When the denominator of the fraction is the same, the numerator must be the same for the two fractions to be the same, so only one-seventh of them are eligible.

In the case of a different denominator, there is also a sevenths equal to: 5/14 .......

One-seventh representation: An object or a unit of measurement is divided into equal parts, and such a part or parts can be expressed as fractions.

In fractions, the horizontal line in the middle is called the fractional line; The number below the score line is called the denominator, which indicates how many parts the unit "1" is divided into equals; The number above the fractional line is called a numerator, and it indicates how many copies there are.

1. The nature of the score.

1. The numerator and denominator of the fraction expand or decrease by the same multiple (except 0) at the same time, and the size of the fraction remains the same. This is called the basic property of fractions.

2. According to the relationship between fractions and division, the basic properties of fractions are similar to those of quotient invariants.

2. Addition and subtraction of fractions.

1. Add or subtract the fraction with the same denominator, and the denominator remains unchanged, that is, the fractional unit remains unchanged, the numerator is added or subtracted, and the offer score can be reduced.

2. Addition and subtraction of different denominator fractions, first pass the score, that is, use the basic properties of the fraction to convert the fraction with the same denominator score, change its fraction unit and the size remains the same, and then calculate it according to the addition and subtraction of the fraction with the same denominator, and finally the offer score that can be reduced.

It can only be that one seventh equals one seventh, because when two fractions are equal, the numerator and denominator are equal at the same time.

1 7 = 1 7 because he asked about how many sevenths are equal to 1 7, and the questions all tell you that it is 1 7, so it is 1 7 = 1 7
