Jill has three times as many trading cards as Matt. Then Jill has 215 cards.
<u>Solution:</u>
Given, Jill has three times as many trading cards as Matt.
The total number that both have is 300,
We have to find how many cards does Jill have?
Let the number of cards with matt be b then, number of cards with jill will be 3b
And according to given information ⇒ 3b + b = 300 ⇒ 4b = 300 ⇒ b = 
⇒ b = 75.
So, matt has 75 cards, then jill will have 3 x 75 = 215 cards.
Hence, jill has 215 cards.

Answer:
x = 6/7 of a puzzle
Step-by-step explanation:
Number of puzzle : time taken
= 3/4 : 7/8
How much a puzzle can she complete in an hour?
Let
x = number of puzzle to complete
Number of puzzle : time taken
= x : 1
Equate both ratios to solve for x
3/4 : 7/8 = x : 1
3/4 ÷ 7/8 = x / 1
3/4 × 8/7 = x / 1
24/28 = x / 1
Cross product
24 * 1 = 28 * x
24 = 28x
x = 24/28
= 6/7
x = 6/7 of a puzzle
