# Tailor

Tailor has an estimated 11 meters of 80 cm wide fabric. He will shape wholly 7 rectangles measuring 80 x 150 cm and nothing fabric does not remain. How many fabric he have?

Result

x =  10.5 m

#### Solution:

$a=150/100=\dfrac{ 3 }{ 2 }=1.5 \ \\ b=80/100=\dfrac{ 4 }{ 5 }=0.8 \ \\ x<11 \ \\ x=7 \cdot \ a=7 \cdot \ 1.5=\dfrac{ 21 }{ 2 }=10.5 \ \text{m}$
