Question

Please help. Can't get calculator to work solve for x. Look at the picture.

Answer 1

Hey there!

4/5 = x/9

CROSS-MULTIPLY the fractions

4 * 9 = x * 5

4 * 9 = 5 * x

SIMPLIFY IT!
36 = 5x

5x = 36

DIVIDE 5 to BOTH SIDES

5x/5 = 36/5

SIMPLIFY IT!
x = 36/5

Therefore, the answer should be:
x = 36/5

Good luck on your assignment & enjoy your day!

Answer 2

$\boxed{ \boxed{\bf x= \cfrac{36 }{5} }\bf \: or\:\boxed{\bf x= 7.2}}$

Step-by-step explanation:

$\bf \cfrac{4}{5} = \cfrac{x}{9}$

We first need to multiply both sides by 9.

• $\bf \cfrac{4}{5} \times 9 = x$

Let's put 4/5 × 9 as a single fraction.

• $\bf \cfrac{4 \times 9}{5} = x$

Multiply 4 and 9 = 36

• $\bf x= \cfrac{36 }{5} \: \: or\: \: x=7.2$
