Answer:
180
Step-by-step explanation:
What you have to do is multiply all of them.
9 x 4 x 5 = 180
15 3/4% = 15.75%
15.75% = 0.1575
The answer is A.
Got a calculator? all you do for #1 and #2 is multiply the two numbers and that is the value for x.
These problems are cross multiplication.
For the next two:
.25x = 6
divide both sides by .25
x = 24
NEXT ONE:
.49x = 12
divide both sides by .49
x = 24.48
