The LCD is 40:\n(7/10*4/4)-(7/8*5/5)\n28/40-35/40=-7/40

Not sure what you mean but as for 2.5/28.8=x/691.2\n\n2.5*691.2/28.8=x\n\nlooks like 60  to me

8 2/5 = [(8*5)+2]/5=42/5\n\n7/(42/5)= (7*5)/42= 35/42

7/8 divided by .25 is the same as multiplying by 4. \n7/8 X 4 = 28/8 = 3 4/8 = 3 1/2

it's easy of means multiply something the .7  is in precent and u have to convert it into a decimal by moving the decimal point 2 spaces to the left. the answer to the problem is.9093. I think u are missing some infor u probably want a fraction like is/for = %/whole I can't do that because u have not provide me with details.

You should change alll of them into improper fractions.....so.....\n\n216/72-103/72\n\nYour answer should equal\n93/72 or 1 21/72 or 1 7/24\n\nHope this helps!

30 divided by 1/2 is the same thing as 30 times 2 = 60\n60 plus 10 is 70.

1/2*1/4*1/10 = 1/80\n\n=> 1/80 of 800 = 800/80 = 10\n\nso, one half of one quarter of one tenth of 800 is 10.

You use cross multiplication.\n1/2, 5/8, 6/*, 3/4 \n\nYou multiply the numerator of one fraction to the denominator of the other fraction you're comparing it with. For example, you cross multiply 1/2 and 5/8.\n\n1*8 = 8 so lets say 1/2 got 8\n5*2= 10 so 5/8 got 10. Therefore, 5/8 is greater than 1/2

maybe i can help you understand that question.  First turn that into an inproper fraction by saying 8 times 10 is 80 plus 3 equals 83, so now you have a fraction 83/8.  \n\nNext you need to have common demons lol which is 8. to make 3/4 with an 8 as the demon you have to multiply the 4 by 2 and also the 3, Therefore you have 83/8-6/8.  Now just subtract the two.  \n\nThat will give you 77/8.  Now you must make that a proper fraction by dividing 8 into 77, which gives you 9 and a remainder of 5.  \n\nTherefore you now have 9 and 5/8. Hope that helps.

Find the difference between each number and 2/7, you get:\n\n2/7 - 0   = 0.285 - 0.0 = 0.285\n1/2 - 2/7 = 0.5 - 0.285 = 0.215\n1 - 2/7   = 1.0 - 0.285 = 0.715\n\n\nAs difference between 1/2 and 2/7 is the least, 2/7 is closest to 1/2.
