A fifth of a kilogram is a fraction of a quarter of a kilogram
One fifth of a kilogram is equivalent to (1 / 5) / (1 / 4) = 4 / 5 of a quarter of a kilogram
If 1 / 5 of a is equal to 1 / 9 of E, then 1 / 4 of a is equal to what part of B?
a/5=b/9
a=5b/9
Multiply both sides by 1 / 4
a/4=5b/36
One fifth of a is equal to one fourth of B. compare the size of a and B
Unknown sign, insufficient condition
If it is a short answer question, please discuss > 0 = 0
A quarter is greater than B of a, B of a is greater than one fifth, a plus B equals seventeen, what is a and what is B
The reason is as follows: 1 / 5 < B / a < 1 / 4, so 4B < a < 5b, so 5B < A + B < 6B, that is 5B < 17 < 6B, so B can only take integer 3, a = 14,
