Answer:
1 2/3
Step-by-step explanation:
Luis mixed all the trails thus:
4 2/3 + 1 1/4 + 1 1/3 + 3/4
= 15/3 + 5/4 + 4/3 + 3/4
= 60+15+16+9/12
Total trail mixed by Luis equals 100/12
He then divided 100/12 among his 5 friends thus:
100/12 ÷ 5
= 20/12
= 1 2/3 per friend.
212 m²
4 x 4 x 5 = 80
6+6+50+30+40
x = -11
−3x + 6 = 39
-3x = 33
