U count how many zeros are in each of the problems then u multiply the whole number and add the zeros to the end

example 500 x 400 = 200000 because 5 x 4 is 20 and 500 and 400 have 2 zeros each so u add 4 zeros to 20 so 200000

Because you do 5 times 4 just like you would with the first one and just bring the zeros down from the 500 and 400

Easy question i will mark braineliest

Answer:

<h2>0.67</h2>

Step-by-step explanation:

5(y - 3.8) = 4.7(y - 4)

Distribute 5 through the parentheses

5y - 19 = 4.7(y - 4)

Distribute 4.7 through the parentheses

5y - 19 = 4.7y - 18.8

Move ' 4.7 y ' to L.H.S and change it's sign

5y - 4.7y - 19 =  - 18.8

Move constant to R.H.S and change it's sign

5y - 4.7y =  - 18.8 + 19

Collect like terms

0.3y =  - 18.8 + 19

Calculate

0.3y = 0.2

Divide both sides of the equation by 0.3

\frac{0.3y}{0.3}  =  \frac{0.2}{0.3}

Calculate

y = 0.67

Hope this helps...

Best regards!!
