$14 9/10

Step-by-step explanation:

Ruby had 30 dollars to spend on 3 gifts. She spent 9 7 10 dollars on gift A and 5 2 5 dollars on gift B. How much money did she have left for gift C?

From the above question,

$30 = Gift A + Gift B + Gift C

She spent 9 7/ 10 dollars on gift A and 5 2/5 dollars on gift B.

$30 = $9 7/10 + $5 2/5 + Gift C

Gift C = $30 - ( $9 7/10 + $5 2/5)

Lowest Common Denominator = 10

Gift C = $30 - $14+(7 + 4/10)

Gift C = $30 - $14+(7 + 4/10)

Gift C = $30 - $14+(11/10)

$30 - $14+(1 1/10)

$30 - $15 1/10

Gift C = $14 9/10

Therefore, the amount of money she had left for gift C is $14 9/10

answer: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.
