How do I divide I don’t know how to it’s so confusing and how do you do the remainders
podryga [215]

Answer:

Step-by-step explanation:

set up the problem long division 487 divided by 32 Set up the division problem with the long division symbol or the long division bracket.

Put 487, the dividend, on the inside of the bracket. The dividend is the number you're dividing.

Put 32, the divisor, on the outside of the bracket. The divisor is the number you're dividing by.

step 1 divide dividend by divisor in long division 487 divided by 32 Divide the first number of the dividend, 4 by the divisor, 32.

4 divided by 32 is 0, with a remainder of 4. You can ignore the remainder for now.

step 2 subtraction in long division problem 487 divided by 32 Put the 0 on top of the division bracket.

This is the beginning of the quotient answer.

Next, multiply 0 by the divisor 32 and insert the result 0 below the first number of the dividend inside the bracket.

0 * 32 = 0

step 3 long division 487 divided by 32 Draw a line under the 0 and subtract 0 from 4.

4 - 0 = 4

step 4 long division 487 divided by 32 Bring down the next number of the dividend and insert it after the 4 so you have 48.

step 5 long division 487 divided by 32 Divide 48 by the divisor, 32. The answer is 1. You can ignore the remainder for now.

48 ÷ 32 = 1

Note that you could skip all of the previous steps with zeros and jump straight to this step. You just need to realize how many digits in the dividend you need to skip over to get your first non-zero value in the quotient answer. In this case you could divide 32 into 48 straight away.

step 6 long division 487 divided by 32 Put the 1 on top of the division bar, to the right of the 0. Next, multiply 1 by 32 and write the answer under 48.

1 * 32 = 32

step 7 long division 487 divided by 32 Draw a line and subtract 32 from 48.

48 - 32 = 16

step 8 long division 487 divided by 32 Bring down the next number from the dividend and insert it after the 16 so you have 167.

step 9 long division 487 divided by 32 Divide 167 by the 32. See a pattern emerging?

167 ÷ 32 is 5 with a remainder of 7

step 10 long division 487 divided by 32 Put the 5 on top of the division bar, to the right of the 1. Multiply 5 by 32 and write the answer under 167.

5 * 32 = 160

step 11 long division 487 divided by 32 Draw a line and subtract 160 from 167.

167 - 160 = 7

step 11 long division 487 divided by 32 Since 7 is less than 32 your long division is done. You have your answer: The quotient is 15 and the remainder is 7.

So, 487 ÷ 32 = 15 with a remainder of 7

For longer dividends, you would continue repeating the division and multiplication steps until you bring down every digit from the divdend and solve the problem.

Clara earns at least $36.75 but not more than $98 working. She earns $12.25 per hour. The number of hours it takes Clara to earn
Trava [24]
36.75 \leq p \leq 98
t(p)= \frac{p}{12.25}
\\t(36.75)= \frac{36.75}{12.25} =3
\\t(98)= \frac{98}{12.25} =8
\\3 \leq t(p) \leq 8
