1 5/7÷4/9 = what's the answer and how to write the problem out
balu736 [363]

The solution to given expression 1\frac{5}{7} \div \frac{4}{9} is \frac{27}{7} or 3.8571

<em><u>Solution:</u></em>

Given expression is:

1\frac{5}{7} \div \frac{4}{9}

<em><u>First let us convert the mixed fraction to improper fraction</u></em>

Multiply the whole number by the denominator.

Add the answer from Step 1 to the numerator.

Write answer from Step 2 over the denominator.

Thus we get,

1\frac{5}{7} = \frac{1 \times 7 + 5}{7} = \frac{12}{7}

Now the given expression becomes,

1\frac{5}{7} \div \frac{4}{9} = \frac{12}{7} \div \frac{4}{9}

Convert the problem to multiplication by changing the division sign to multiplication and inverting the fraction to the right of the sign

\frac{12}{7} \div \frac{4}{9} = \frac{12}{7} \times \frac{9}{4}

Multiply the numerators, multiply the denominators, and leave the product in factored form

\frac{12}{7} \times \frac{9}{4} = \frac{27}{7}

In decimal form we get,

\frac{27}{7} = 3.8571

Thus the solution to given expression is \frac{27}{7} or 3.8571
