How do you solve 3 1/4- 1 7/8 step by step?
Vilka [71]

Answer:

1 3/8.

Step-by-step explanation:

3 1/4 - 1 7/8

First convert to improper fractions:

3 1/4 = (3*4) + 1 / 4 =  13/4.

1 7/8 = (1 *8)+7 / 8 = 15/8. So we have:

13/4 - 15/8

The Lowest Common Multiple of 4 and 8 is 8 so we convert 13/4 to eighth's

13 / 4 = 13*2 / 4 *2 = 26/8

Finally: we have

26/8 - 15/8 = (26 - 15) /8

= 11 /8

= 1 3/8 (answer)

poizon [28]

Let the amount saving by Sienna and Jacob be x

Sienna has $8 and is saving $3 per week

So the equation will be 3x + 8

Jacob has $6 and is saving $4 per week

So the equation will be 4x + 6

Sienna will have same amount as Jacob, so

3x + 8 = 4x + 6

So the model two will represents the equation that Sienna will have same amount as Jacob.

The stock of Company A gained 2% today to $27.03. What was the opening price of the stock in the beginning of the day?
Luden [163]

Answer:

The price of the stock in the beginning of the day was $26.5.

Step-by-step explanation:

This question can be solved using a rule of three.

The initial stock of the company, that we want to find, was 100% = 1.

$27.03 is an increase of 2%, so it is 100+2 = 102% = 1.02%. So

$27.03 - 1.02

$x - 1

1.02x = 27.03

x = \frac{27.03}{1.02}

x = 26.5

The price of the stock in the beginning of the day was $26.5.
