U had to take a pic of the work so we could see it
Total of 2.7. ---Anna had 0.5 Sam 0.75 Michelle 0.45 and Paige 0.70
Got a calculator? all you do for #1 and #2 is multiply the two numbers and that is the value for x.
These problems are cross multiplication.
For the next two:
.25x = 6
divide both sides by .25
x = 24
NEXT ONE:
.49x = 12
divide both sides by .49
x = 24.48
