Question

If 60% of a number equals to two-fifth of another number, what is the ratio of first number to second number?

Answer 1

Answer:

$60\%x = (2 \div 5)y \\ (60 \times x) \div 100 = (2y \div 5) \\ cross \: multiplication \\ x \div y =( 2 \div 5) \times (100 \div 60) \\x \div y = 2 \div 3$

therefore x:y=2:3
