Question 1
(8.5 / 100) x 15

= (17/40) x 3
= 51 / 40
= 5.1 / 4
= 1.2 7 5

8.5% of 15.00=
.085 x 15=$1.275
3/4 x 64/1=48
4 becomes 1 and 64 becomes 16 3*16=48

i find working as decimals is easier to understand
1) 8.5% as a decimal is
8.5% divided by 100%
therefore 8.5 divided by 100 = 0.085
0.085 x $15 = $1.275
if you are rounding up to the nearest cent it would = $1.30
2) 3/4 (or 3 quarters) is
3 divided by 4
which = 0.75
0.75 x 64
= 48
hope that helped, and that u understand the logic there :)
