Answer:
x=6/7
Explanation:
It is basically saying x/8/15=45/28
15 can be multiplied by x so it is no longer in the denominator
15x/8=45/28
Cross multiply and isolate x
15x*28=420x
8*45=360
420x/420=360/420
Simplify
36/42 divide by 6 --> 6/7
x = 6/7
x ÷ 8/15 = 45/28
Copy dot flip
x * 15/8 = 45/28
Multiply each side by 8/15
x*15/8 *8/15 = 45/28 * 8/15
x = 45/28 * 8/15
Rewriting
x = 45/15 * 8/28
x = 3/1 * 2/7
