How are we supposed to do it like we're in 5th grade if we're not in 5th grade? I'm in 8th so it is really sad that I didn't understand the problem at all.
1.Calculate:
A-B=725, A/B=37,5
A/B=37,5
A=?
B=?
No decimals
With how to solve
A - B=725
A=725 + B, but we have,
(725+B)/B=37.5 cross multiply
725+B=37.5B isolate B to one side
725=37.5B-B
725=36.5B divide both sides by 36.5
B=725/36.5
B=1450/73 and
A=54,375/73. YOUR ANSWER IS IN FRACTIONS, WHICH YOU CAN TURN INTO DECIMALS.
A-B=725
A/B=37.5 A=37.5B
37.5B-B=725
36.5B=725
B=1450/73 or 19.863013698630137
A=37.5B=744.8630136986301375
i think it need to be like that
I have never learned what / means if it is common core no wonder I go to a school where they don't do that.
