Turn both into improper fractions- there easier to work with that way
3 15/16 — 63/16
2 1/4 — 9/4
Then, set it up- you multiply by the reciprocal
63 Divided by 9
__. __
16. 4
Multiply by reciprocal (flipped-second fraction)
63. x. 4
16 9
Cross product- check to see if diagonally the numbers have similar factors- 63 and 9 have 9 in common, 16 and 4 have 4 in common
7. 1
4. 1
1 3/4
12.7 because you use the pythagoreom theory which states a^2+b^2=c^2 and you use algebra to get a by itself and solve
The first number subs for x and the second number subs for y
Answer:
<h3>D</h3>
Step-by-step explanation:
Lets work backwards, he had $5 after it all, and spent $1.25 on a snack, so we add that to the remainder, which is $6.25. then he spent half of that on whatever stuff he likes, so add $6.25 and $6.25, which is $12.50
