(4.8)/(1 (7)/(9))=(1.2b):6 (2)/(3) so basically
4.8 over 1 7/9
equals
1.2b : 6 2/3
ty<3

b=15

Step-by-step explanation:

First of all, let's change those mixed numbers to improper fractions to make this a little easier.

1 7/9 = (1*9 + 7)/9 = 16/9

6 2/3 = (6*3 + 2)/3 = 20/3

Now we can also change the decimals to fractions.

4.8 = 4 8/10 = 48/10 = 24/5

1.2 = 1 2/10 = 12/10 = 6/5

Now we rewrite the entire thing to get:

(24/5)/(16/9)=(6/5)(b)/(20/3)

Rewrite the fraction division as multiplying by the reciprocal and you have:

(24/5)*(9/16)=(6/5)*b*(3/20)

Multiply the fractions and simplify.

54/20=(9/50)*b

Divide by 9/50 on both sides (which is the same as multiplying by 50/9).

(54/20)*(50/9)=b

Simplify to get:

b=15

It should be way easier if you have a calculator; divide 4.8 by 1 and 7/9, then multiply by 6 and 2/3, and finally, divide by 1.2.
