Answer:
The total fabric needed for 2¼ yards of material and 1¼ yards of linen is 3½ yards
Step-by-step explanation:
Given
Let M = Size of material
M = 2¼ yards
Let S = Size of linen
S = 1¼ yards.
Quantity of fabric needed is calculated by adding the size of material to the size of linen.
Let T represent total quantity of fabric need
T = M + L
By substituton,
T = 2¼ yards + 1¼ yards
Convert to improper fraction
T = 9/4 yard + 5/4 yards
Find LCM (Least Common Multiple)
LCM = 4..
So, T = 9/4 yard + 5/4 yards becomes
T = (9 + 5)/4 yards
T = 14/4 yards
T =(7*2)/(2*2) yards
T = 7/2 yards
Convert to mixed fraction.
T = 3½ yards or 3.5 yards
The total fabric needed for 2¼ yards of material and 1¼ yards of linen is 3½ yards
