Question

2 1/7:(15a)=5 1/4:(0.8)

Answer 1

Answer:
`a=0.021`

Explanation:

1. To solve the expresion given in the problem above you must apply the following proccedure:

- Convert mixed numbers to decimals. Divide the numerator and the denominator of the fraction part and add the result to the whole part:

`2+(1)/(7)=2+0.14=2.14`

`5+(1)/(4)=5+0.25=5.25`

- Rewrite the expression:

`(2.14)/(15a)=(5.25)/(0.8)`

- Now, you can solve for
`a`:

`0.14=6.56a\\a=(0.14)/(6.56)\\a=0.021`
