You can also break it into tens and ones:

30+7+1+1+1+1+1+1+1+1

30+7=37

1+1+1+1+1+1+1+1=8

Justin bought some yarn from his favorite craft store. He can make one scarf with 3/5 of a ball of yarn. If he purchases 15 ball
Elena L [17]

He can make 25 scarves from 15 balls of yarn.

Step-by-step explanation:

Given,

Yarn used for one scarf = \frac{3}{5} of a ball

Yarn purchased = 15 balls

Let,

x be the number of scarves.

Yarn used for one scarf*number of scarves = Yarn purchased

\frac{3}{5}x=15

Multiplying both sides by \frac{5}{3}

\frac{5}{3}*\frac{3}{5}x=15*\frac{5}{3}\\x=\frac{75}{3}\\x=25

He can make 25 scarves from 15 balls of yarn.

A rational number is such that when you multiply it by 5/2 and add 2/3 to the product, you get 7/12. What is the number?
Afina-wow [57]

Answer:A rational number is such that when you multiply it by 5/2 and add 2/3 to the product you get -7/12 . What is the number.

Step-by-step explanation:Let p/q (q ≠ 0) denote the rational number. Multiplying it by 5/2 gives (p/q)(5/2). Add 2/3 to the product and we get (p/q)(5/2) + 2/3 . The result is given to be -7/12.

∴ (p/q)(5/2) + 2/3 = -7/12 …………………………..……………………………………..(1)

Transposing 2/3 to right-hand-side and changing the sign to negative,

(p/q)(5/2) = -2/3 -7/12 = -(2/3 + 7/12) =- (2 x 4 + 7)/12 (Taking L.C.M.)

Or, (p/q)(5/2) = -(8+7)/12 = - 15/12

Multiplying both sides by 2/5,

(p/q)(5/2) x (2/5) = -15/12 . 2/5 = -(3x5)/(3x4) . 2/5 =- 5/4 .2/5

Since 2/5 is the multiplicative inverse of 5/2, 5/2 x 2/5 = 1 and we obtain

(p/q).1 = -1/4 . 2/1 = -1/2

⇒ p/q = -1/2 which is a negative rational number in which p = 1 and q = 2 ≠ 0 .

∴ the rational number = -1/2

What is the solution to the equation fraction 4 over 5 n minus fraction 3 over 5 equals fraction 1 over 5 n?
Andreas93 [3]

Answer:

The solution is n=1

Step-by-step explanation:

I hope you mean

4/5n-3/5=1/5n

if so then here's the solution

5n×4/5n-3/5×5n=1/5n×5n

4-3n=1

4-1=3n

3n=3

n=1
