HELP ME OUT PLEASE!! -Find the number: 25% of a number is a lb.

I’m going to generalise the answer in the hope of preventing a billion questions with the % changed a little.

If you have a calculator X% just means multiply by X and divide by 100.

If you don’t have a calculator or paper handy, you can split the problem: I’ll do it for 25% but in this case the other answers are simpler.

25%=10%+10%+5%.

Now 10% is easy, just move the decimal one place to the left, for instance 35 becomes 3.5.

5% is half of 10% 3.5/2=1.75

Add it all up: 3.5+3.5+1.75= 8.75. Done.

You don't even need to know multiplication above 5x tables, for instance

37% is 10%+10%+10%+7% but that requires multiplying by 7.

37% is also 10%+10%+10%+10% -3% only requiring 3x table.

I'm not sure if this is what you mean but here ya go

25%=

25/100

25/100 * 1/1

100 * 1/25*1=

100/25=

4

Step-by-step explanation:

12r - 8 - 12

you have to combine like terms. below i have bolded the like terms:

12r - 8 - 12

together it combines to:

12r - 20

hope this !

85.3-64 = 21.3

so laura has already added 85.3 grams of chocolate powder and she has gone over the amount specified in the recipe by 21.3 grams

hope i ! have a great  day!
