If the current volume is x then the question can be rewritten as: 10%x/(x+a) = 1% where a is the amount of water you need to add. Multiply both sides by x+a and you get 10%x = 1%x + 1%a Subtract 1%x from both sides and get 9%x = 1%a Divide by 1% and you get 9x = a Thus, to make a 1 percent solution from a 10 percent solution, you need to add 9 times the current volume of the solution in water.
1/5 + 1/5 + 1/10 need common denominator to add fractions; 10 looks good and 1/5 = 2/10 2/10 + 2/10 + 1/10 = 5/10 which is........... = 1/2
You need to add 7 (or +7)
You add 10 to -7 to get 3.
17
you need to add 3/10 to 7/10 to get 10/10 or 1.
10
11
You need to add 18 to negative 8 to get 10.
you need to add 10
yes
your expression is this... x + -10 = 2 x = 12 You need a 12 to add to -10 to get 2

-10 + 20 = 10 because you need 10 to get 0 and 10 more to get +10

VAT is 17.5% so to add that to a price you do this. Say a top is £10.00. You need 10% which is £1. 5% is 50p. and 2.5% is 25p so: 10%---£1.00 5%--- 50p 2.5%--- 25p ---- £1.75 So 1.75 add 10.00 is 11.75 VAT is 17.5% so to add that to a price you do this. Say a top is £10.00. You need 10% which is £1. 5% is 50p. and 2.5% is 25p so: 10%---£1.00 5%--- 50p 2.5%--- 25p ---- £1.75 So 1.75 add 10.00 is 11.75
15-10 = 5
