Find the least common multiple which is 24
3.7÷(1 2/9 −0.4) = 166.5/45 ÷ 37/45 = 4.5
0.4 = 40/100 = 2/5
2/5 = 18/45
1 2/9 = 11/9 = 55/45
55/45 - 18/45 = 37/45
3.7 = 370/100 = 18.5/5 = 166.5/45
ANSWER: 4.5
Hi friend,
The objective is to divide $20 in 2:3 ratio.
One part be 2x, another part is 3x
Sum of them = 20
2x + 3x = 20
5x = 20
x=4
So therefore one part must be 2x = 2 x 4 = 8
Another part = 3x = 3 x 4 = 12
Hence it is divided in 2:3 ratio.
Hope my answer is helpful to u. :)
