bulgar [2K]

Answer:

35, 35, and 50

Step-by-step explanation:

50 + x + x = n

n ÷ 3 = 40

n = 40 x 3

n = 120

50 + 2x = n

50 + 2x = 120

2x = 120 - 50

2x = 70

2x/2 = 70/2

x = 35

To check:

35 + 35 + 50 = 120

120 ÷ 3 = 40

Hope this helps

stealth61 [152]
If u do the inverse and switch the 5/8 to 8/5 cause of (KCF- keep change flip) then u would get
\frac{1}{4}  \times  \frac{8}{5}
Then u would cross divide (basically asking yourself) to find the greatest factor u can multiply with two numbers if u can if u can only find one do one
how many times can 4 go into 4? which is 1
And how many times can 4 go into 8 which is 2 which is
\frac{1}{1}  \times  \frac{2}{5}
