Question

Plz help can’t find the answer

Answer 1

multiply the 2/8 x 4/9 first

then add the 7/9

you'll get 6/9

simplify to get the answer: 2/3

Answer 2

$\frac{7}{9} -\frac{2}{8} \times \frac{4}{9}$

Start by multiplying the fractions together. When multiplying fractions they don't need to have a common denominator, so multiply 2/8 and 4/9 from left to right.

$\frac{2}{8} \times \frac{4}{9} = \frac{8}{72}$

Now your new problem looks like: 7/9 - 8/72. When subtracting fractions they have to have common denominators so multiply 7/9 by 8/8.

$\frac{7}{9} \times \frac{8}{8}= \frac{56}{72}$

You can now subtract 56/72 and 8/72 to get your final answer.

$\frac{56}{72} -\frac{8}{72} = \frac{48}{72}$

This fraction can be simplified by dividing both sides by 8 because the numerator and denominator of this fraction are multiples of 8 and can be divided evenly by 8.

$\frac{48}{72} \div \frac{8}{8} = \frac{6}{9}$

6/9 can be simplified even further by dividing both sides by 3 because both 6 and 9 can be divided evenly by 3.

$\frac{6}{9} \div \frac{3}{3} = \frac{2}{3}$

D) 2/3 is your final answer.
