Jack has twice as many dimes as quarters. If the total value of the coins is $6.30, how many dimes does he have?

ycow [4]

Answer:

Number of dimes = 28

Step-by-step explanation:

Given that:

Worth of coins = $6.30 = 6.30 * 100 = 630 cents

Let,

x be the number of dimes

y be the number of quarters

According to given statement;

x = 2y Eqn 1

10x+25y = 630 Eqn 2

Putting x = 2y in Eqn 2

10(2y) + 25y = 630

20y + 25y = 630

45y = 630

Dividing both sides by 45

$\frac{45y}{45}=\frac{630}{45}\\y=14$

Putting y=14 in Eqn 1

x = 2(14)

x = 28

Hence,

Number of dimes = 28

for the second one, the answer is 2.75

for the third one and fourth one,
To divide fractions take the reciprocal (invert the fraction) of the divisor and multiply the dividend. This is the quickest technique for dividing fractions. The top and bottom are being multiplied by the same number and, since that number is the reciprocal of the bottom part, the bottom becomes one
