HI GUYS!

So today we we're assigned a question from the textbook again and I was assigned, to do #16. If I did anything wrong please tell me. Also, if you don't understand the way I explained it, just tell me and I'll be glad to help you (:

16) Boris has 2 1/2 times as much cash as Anna.
Charlie has 3/4 as much cash as Anna.
Anna has \$25.60 in cash.

a) How much cash do the three people have altogether?
Boris: Since he has 2 1/2 times as much as Anna, I'm gonna find what half of \$25.60 is, then add with whatever 2 x \$25.60 is. I;m multiplying by because 25.60 equals to 1 in this case, so if I multiply that by 2, I would get 2. Then half of 25.60 equals to 1/2 and if I add them together, it would equal to 2 1/2.

\$25.60 x 2 = \$51.20
\$25.60 ÷ 2 = \$12.80

\$51.20 + \$12.80 = \$64.00

Boris has \$64.00

Charlie: Since Charlie has 3/4 times as much as Anna, I'm gonna find what three quarters of \$25.60 is by dividing it by 4, then multiplying the answer to that by 3. I'm dividing by 4 because i want to know what one quarter of 25.60 is. Then when I have 1/4 of 25.60, I can multiply that by 3, to get 3/4.

\$25.60 ÷ 4 = \$6.40
\$6.40 x 3 = \$19.20

Charlie has \$19.20

\$25.60 + \$64 + \$19.20 = \$108.80

The three people had \$108.80, altogether

b)How much more cash does Boris have than Charlie?
Well since Boris has \$64, and Charlie has \$19.20, all you have to do is subtract 19.20 from 64.

\$64 - \$19.20 = \$44.80

Boris has \$44.80 more cash than Charlie.

COMMENT and tell me if I got anything wrong or if you don't understand.
Oh, and I'm sorry if it's really plain, I still don't know why my colours wont show up ):
