How to find the unit rate of 14lb for $2.99

Answers

Okay so let's try to find the amount of money needed to buy 1 lb. Therefore, let's divide the fraction by 14. 
(14)/(2.99) 
Then we'll divide both the numerator and denominator by 14. 
(14)/(2.99) ÷ (14)/(14)
Then we simplify and get:
14÷14=1     2.99÷14=.2135   We can round that to .21
The unit rate for each pound would be 1:.21
I don't know if that helped, but yeah. :)

Look at the units.
If you divide (2.99 dollars) by (14 lb), the quotient will be
(dollars per pound),which is exactly what you want.

3.49 x 2=6.98
6.98+1.40=8.38
20-8.38=$11.62

Second Question
22.50 x 2=45
45+35.50+7.18=87.68
87.68/2=43.84

Winslow buys 1.2 pounds of bananas. The bananas cost $1.29 per pound. To the nearest cent, how much does Winslow pay for the bananas?

Answers

Answer:

1.55 dollars or 155 cents

Step-by-step explanation:

Given :Winslow buys 1.2 pounds of bananas. The bananas cost $1.29 per pound

To Find :   To the nearest cent, how much does Winslow pay for the bananas?

Solution :

Cost of 1 pound of Bananas = $1.29

Cost of 1.2 pounds of bananas =1.29 * 1.2 = 1.548

1 dollar = 100 cents

So, 1.548 dollars = 154.8 cents

Hence  Winslow pay 1.55 dollars or 155 cents for the bananas

 1.2*1.29= $1.55
  lbs*price = cost

There are 12 girls and 16 boys in javier's math class.There are 26 girls and 14 boys in javier's choir class.Is the ratio of girls to boys in the two classes equivalent? Explain

Answers

Answer:

Not equivalent

Step-by-step explanation:

A fraction is a part of whole .

Two fractions are said to be equivalent if their lowest forms are same .'A fraction (a)/(b) is said to be in lowest form if HCF(a,b)=1.

Given :

Number of girls = 12

Number of boys = 16

So, fraction = (Number\,\, of\,\, girls)/(Number\,\, of\,\, boys)

 =(12)/(16)=(2* 2* 3)/(2* 2* 2* 2)=(3)/(4)

Number of girls = 26

Number of boys = 14

So, fraction = (Number\,\, of\,\, girls)/(Number\,\, of\,\, boys)=(26)/(14)=(2* 13)/(2* 7)=(13)/(7)

As (3)/(4)\neq (13)/(7) , these fractions are not equivalent .
These ratios are not equivalent because if you calculate it, they do not start from the same simplified ratio. 12/16 is 3/4 and  26/14 is 13/7 and those two ratios are not equivalent. I hope this helped you
