Not sure if you mean this: (5 + 1/2) * (3 + 3/5)\n\nChange 1/2 into 5/10, and 3/5 into 6/10.\nChange 5 into 50/10, and 3 into 30/10.\n\nYou can now see that the number is: (55/10) * (36/10).\n\nTogether: (55*36) / (10*10), resulting in 1980/100\n\nYou can take out 19 times 100 from 1980; so you get 19+80/100\n80/100 is 8/10 is 4/5.\n\nThe answer: 19 4/5

200 X 35 /100 = 70 That is 200 times the percentage in this case 35 then divide by 100 = 70. To divide by 10 remove one 0, to divide by 100 remove two 0's, etc. Can't explain it simpler than that. lol

x+y=50\n.02x + .05y=1.87\n\nfrom the first equation, subtract y from both sides:\n\nx=50-y\n\nsubstitute this into x in the second equation:\n.02(50-y) + .05y = 1.87\n\nand solve for y\n1-.02y+.05y=1.87\n.03y=.87\ny=29\n\nso there are 29 5 cent coins and 21 2 cent coins.

You repeated your question.\n11/55\n= 1/5\n(1/5)*100 = 20%

5x^2 =100\nx^2 = 100/5\nx^2 = 20\nx = + or - sqr root of 20\n\n(x+8)^2 = 81\nx+8 = 9\nx=1

isn't it to add pairs of mumbers like (1+100) (2+99) (3+98).......(50+51)\n\nall the answers are 101, and there are 50 answers\n\nso 101 x 50 = 5050

% = Out of 100, so you need to find out: 5/100 = ?/2,000\nTo do this, simply divide $2,000 by 100 and multiply it by 5. Since $2,000/100=$20=1% of 2,000, 5% is going to by 5x more, so you multiply it by 5. $20 x 5 = $100\n\n$100 is 5% of $2,000

Solve for x:\n\n8.50/110 = x/150\n\nMultiply both sides by 150, to get:\n\nx = 150*8.50/110 = 11.59\n\nSo the tax on the $150 item is $11.59.\n\n.

20\n\none half of what 50 is 10 less than = 60/2 = 30\n\n20 is 10 more than 10, and 10 less than 30

yes it's correct\nu can use the arithmetic series formula \nor do this\n\n1 + 100 = 101\n2 + 99 = 101\n......\n50 + 51  = 101\n\nSince there are 50 pairs of these numbers and their sum is always 101\nIt's 50 x 101 = 5050

520.\n\nParentheses first:  50+25+25 = 100\n\nNext, multiplication:  100*5 = 500\n\nThen addition: 500+20 = 520
