Seven out of ten tons is one out of two of () tons and one out of three out of four square meters There are 20 boys in the art class, 5 / 6 of the girls. How many girls are there? The telephone charge of Xiaoming's family in September is 24 yuan, which is equivalent to 6 / 7 of that in August. How much is the telephone charge in August? It's 162 pages of a story book. Zhang Yang read 1 / 6 today. What page will he start reading tomorrow? A car has traveled 120 kilometers from place a to place B, equivalent to three fifths of the whole journey?

The first question is that 20 divided by 5 / 6 equals 24
The second question is that 24 divided by 6 / 7 equals 28
The third question 162 times 1 / 6 equals 27, so tomorrow I'll look at page 28, which is 55
The fourth question 120 divided by three fifths is 200 kilometers

2 / 3 × 7 / 4 × 10 / 3

3 / 3 × 10 7
=2x4x3/(3x7x10)
=1x4/(7x5)
=4 / 35 (4 / 35)

7 out of 10 plus 3 out of 4 is 1. What's the number?

(3 / 1-4) △ 7 / 10
=1 / 4 × 10 / 7
=5 out of 14
A: that's 5 out of 14
