Can anyone help me with this?

answer is because 4×10=40

and 98×4= is 392

40,392

0.0076, if you meant 4.125 divided by 0.03125 it would be 132

step-by-step explanation:

first you have to move the decimal in 0.03125 over until its behind the 5 which is 5 places over. now the number is 3125

then you have to move the decimal in 4.125, 5 places over. now the number is 4,112,500.

now you divide like you would normally would and get 0.0076

cross multiplying, we get :

⇒ (3) × (5) = (9) × (x)

⇒ 15 = 9x
