Answer:
x=5 1/4
Step-by-step explanation:
2 1/4= [tex]\frac{9}{4}[/tex]---> [tex]\frac{9}{4}[/tex] divided by 3 to find 1/7x----> [tex]\frac{3}{4}[/tex]=1/7x---> x=21/4---> x=5 1/4
The number is 5¹/₄
3/7 of it is 2 ¹/₄
let the it be represented as A
3/ 7 of A = 2 ¹/₄
3A/7 = 4X2+1/4 = 9/4
3A/7= 9/4
cross multiply
3A X4 = 9x7
12A = 63
A = 63/12 = 21/4= 5¹/₄
