Now, convert the improper fraction into decimal, by dividing numerator by denominator, we get

Hence, the weight of her backpack in decimal = 7.625 pounds.
The third and last option. To solve the equation we take the reciprocal of 3/4 because you cannot divide fractions so it would be 15• 4/3, but flip this it could also be 15 divided by 3/4 you would just need to further simply the expression
Answer: Yes, and the numbers are 4, 36, and 9
Step-by-step explanation:
Yes, because it x=4, y=36, and z=9 then 4 * 36=144, 144=12*12 4*9=36, 36=6*6, and 9*36=324, 324=18*18. As you can see they are all perfect squares and 4, 36, and 9 are all perfect sqaures too.
