Explain , equivalent fractions, Least common denominator

Mathematics
1 answer:
Volgvan3 years ago
6 0

Equivalent fractions are those fractions that when simplified, are the same.  They reduce to the same fraction in their simplest form.

For example,  12/15 and 24 /30  are equivalent fractions.  They both reduce to 3/5 in their simplest form.


Least common denominator: it is the lowest number you can use in the denominator to create a set of equivalent fractions that all have the same denominator.  

For example, if you have 3/5 + 1/4 and want to add them, you need to get a common denominator

3/5 = 6/10 = 9/15=12/20

1/4 =2/8=3/12 =4/16=5/20

We can use equivalent fractions to help us find the common denominator of 20

replace 3/5 with 12/20 and 1/4 with 5/20  

3/5 + 1/4 = 12/20 + 5/20 = 17/20

Douglas invests money in two simple interest accounts. He invests three times as much in an account paying 14% as he does in an
Rainbow [258]

Douglas invested $ 1300 altogether

<em><u>Solution:</u></em>

Let x represent the amount invested in the account paying 14% interest.

Let y represent the amount invested in the account paying 5% interest

He invests three times as much in an account paying 14% as he does in an account paying 5%

Which means,

x = 3y

<em><u>The simple interest is given by formula:</u></em>

S.I = \frac{p \times n \times r}{100}

Where,

"p" is the principal

"n" is the number of years

"r" is the rate of interest

<em><u>He earns $152.75 in interest in one year from both accounts combined</u></em>

Therefore,

Combined S.I = 152.75

n = 1 year

<em><u>Considering the account earning 14% interest:</u></em>

S.I = \frac{3y \times 14 \times 1}{100}\\\\S.I = 0.42y

<em><u>Considering the account earning 5% interest:</u></em>

S.I = \frac{y \times 5 \times 1}{100}\\\\S.I = 0.05y

<em><u>Since, Combined S.I = 152.75</u></em>

Therefore,

0.42y + 0.05y = 152.75

0.47y = 152.75

Divide both sides by 0.47

y = 325

Therefore,

x = 3y

x = 3(325)

x = 975

<em><u>how much did he invest altogether?</u></em>

Amount invested together = x + y = 975 + 325 = 1300

Thus he invested $ 1300 altogether
