1 1/4x = 3/4
5/4x = 3/4
x = (3/4) / (5/4)
x = 3/4 * 4/5
x = 12/20 which reduces to 3/5

check..
1 1/4 * 3/5 =
5/4 * 3/5 =
15/20 reduces to 3/4

so u would multiply 1 1/4 by 3/5 to get 3/4

I'd suggest dividing. so, what you do is you put 5/4 x 4/3 (thats how dividing works) and you get 20/12 which, when simplified, is 1 2/3.

Answer:

Step-by-step explanation:

1). $((3^2)^{3} )^{\frac{1}{3} }$ = 3² = 9

2). $(x^{3} )^{\frac{2}{3} }$ = 4² = 16

3). $((15^{3} )^{\frac{1}{3} } )^{2}$ = 15² = 225

4). $((21^{3} )^{\frac{1}{3} } )^{2}$ = 14² = 196 (Sorry I made a mistake, the base should be 14)

5). $(5^{3} )^{\frac{2}{3} }$ = 25

6). ( $(16^{3} )^{\frac{1}{3} }$ )² = 256

It starts at $500, then decreases by 30% so just multiply 500 by .7, then multiply the answer by .7, and so on until you get to $84.
