6/15 = 2/5 = 4/10 = 0.4 = 40% of the fruit are apples
divide both 6 and 15 by 3 to get 2/5. Multiply both 2 and 5 by 2 to get 4/10
or just plug 15 and 6 into a calculator with the division key
in decimal form the fraction of apples is 0.40 Multiply that by 100 to get the percentage
0.40 x 100 = 40%. Or just think of it as moving the decimal point two positions to the right.
