1. To get the decimal, you divide 8 by 7 and add that to the back of ten. One eighth is .125. .125*7= 0.875, so your answer is 10.875.
2. A fifth is .2, so your answer is 9.8.
3. One ninth is .11..., which that repeating forever, so 8/9 is .89. You round the last eighth up.
4. 11 goes into 24 twice. Subtract 22 to get 2. Add a decimal and a zero. 11 goes into 20 once. Subtract 11 to get 9. Add another zero. 11 goes into 90 8 times. Subtract 88 to get 2. So your answer is 9.2. Sorry, it's hard to do long division on Brainly haha.
5. 6/27 is equal to 3*2/3*9, which is equal to 2/9. 2/9s is .22...
6. I can't see this one.
7. 8.7/1.4 is basically your problem. Move over the decimals in both of them so that you have 87/14 so that you can actually divide. So put them in long division format, and add a zero so you have 140. 87 goes in once, and you subtract 87 from 140 to get 53. Add another zero. 87 goes into 530 six times. Subtract 522 to get 8. Round .16 to .2 Your answer is .2
8. I'll teach you a fun property. Dividing is the same as multiplying by the reciprocal of something - or the upsidedown version. So if you have .1/1, then you multiply .365 by 1/.1. When you divide by .1, you get 3.65.
9. Do the same thing here. .01/1 flipped is 1/.01. You get 4270.9.
10. Move the decimal over the left three times: .00247
11. Move the decimal over to the left three times: .00039
12. Can't read all of this one.
Hope I helped!
