Let the no. of girls be x and boys be y......
x/y=1/3
=>3x=y            ...............(I)
now 4 boys leave the class is then
x/y-4=2/5
=>5x=2y-8
(I)=>5x=2(3x)-8
x=8
now 3x=y
=>y=24
therefore no. of girls is 8 and the no. of boy is 24..............

Answer:
1. 3/10 is equal to .3 or 30%
2. 7/10 is equal to .7 or 70%
3. The distributive property of multiplication over addition can be used when you multiply a number by a sum. For example, suppose you want to multiply 3 by the sum of 10 + 2. 3(10 + 2) = (30 +20) you can distribute the value outside of the parentheses to the values inside.
