If the difference between a and B is 20 and 15 of a is equal to 16 of B, then the number of a is 20______ ．

15x △ 16-x = 20, & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; 65x-x = 20, & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; 15x △ 15 = 20 △ 15, & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; & nbsp; X = 100, a: the number of a is 100. So the answer is: 100

How much is x minus five sixths

5x-6 / 6
=(1-5 / 6) x
=6 x

One sixth is a fraction plus a fraction. The more, the better,

1/6=1/18+1/9
1/6=1/24+1/8
1/6=1/15+1/10

One sixth is equal to a fraction minus a fraction. One sixth is equal to a fraction plus a fraction plus a fraction. Fill in the brackets with different numbers

One sixth is two sixths minus one sixth
1 is one third plus one third plus one third

Practical problems (with formulas)
1. The original price of a and B shirts is the same. Last October, a village shirt was sold at a 50% discount, B shirt was sold at a 60% discount. Dad bought one of these two kinds of shirts and shared 132 yuan. How much was the original price of these two kinds of shirts

The original price is set at x yuan
The selling price of type a shirt is 0.5x
The selling price of type B shirt is 0.6x
The total cost is 0.5x + 0.6x = 132
So 1.1 x = 132
X = 120 yuan
