Question

Can you help me And if you have all of the can I have them

Answer 1

Answer:

see explanation

Step-by-step explanation:

(6)

we have to calculate the product

$\frac{4}{5}$ × $\frac{5}{8}$

cancel the 5's and the 4/8 by dividing both by 4

= 1 × $\frac{1}{2}$ = $\frac{1}{2}$

(7)

To divide 2 fractions follow the steps

• Leave the first fraction

• Change division to multiplication

• Turn the second fraction upside down

• Simplify, by cancelling if possible

First, however is to change the mixed number to an improper fraction

5 $\frac{1}{3}$ = $\frac{16}{3}$, hence

$\frac{16}{3}$ × $\frac{9}{4}$ (cancel 16/4 and 3/9 )

= $\frac{4}{1}$ × $\frac{3}{1}$ = 4 × 3 = 12

(8)

3 $\frac{1}{2}$ = $\frac{7}{2}$, hence

$\frac{9}{10}$ × $\frac{2}{7}$ ( cancel 2/10 )

= $\frac{9}{5}$ × $\frac{1}{7}$

= $\frac{9(1)}{5(7)}$ = $\frac{9}{35}$
