Question

15.2·0.25−48.51÷14.7/x = ( 13/44 − 2/11 − 5/66 ÷2 1/2 )·1 1/5 / 3.2+0.8·(5 1/2 −3.25)

Plz answer soon. I need it urgently. Need by today. Will give 15 points.

Answer 1

x = 25

Explanation:

15.2 * 0.25 - 48.51 ÷ 14.7 = 76/5 * 1/4 - 3.3 = 3.8 - 3.3 = 0.5

(13/44 - 2/11 - 5/66 ÷ 2 1/2) * 1 1/5 = (13/44 - 8/44 - 5/66 * 2/5) * 6/5 = (15/132 - 4/132) * 6/5 = 11/132 * 6/5 = 1/12 * 6/5 = 1/10

3.2 + 0.8 * (5 1/2 - 3.25) = 3.2 + 4/5 * (22/4 - 13/4) = 3.2 + 9/5 = 3.2 + 2.8 = 5

So after doing all this simplifying and stuff we get 0.5/x = 0.1/5. Using the butterfly method the result is 0.1x = 2.5, multiply both sides by 10 and you get x = 25!! Yayy lol
