The number a is smaller than the number b by 1/5 of b. By what part of a is b bigger than a?

Ira Lisetskai [31]

Answer:

The number b is bigger than the number a by $\dfrac{1}{4}$ of a.

Step-by-step explanation:

1. If the number a is smaller than the number b by 1/5 of b, then

$a+\dfrac{1}{5}b=b.$

Thus,

$a=b-\dfrac{1}{5}b=\dfrac{4}{5}b,\\ \\b=\dfrac{5}{4}a.$

2. Consider the expression $b=\dfrac{5}{4}a:$

$b=\dfrac{5}{4}a=\dfrac{4}{4}a+\dfrac{1}{4}a=a+\dfrac{1}{4}a.$

This gives you that the number b is bigger than the number a by $\dfrac{1}{4}$ of a.

Order these from least to greatest: .25, 3/8, 7/12, 5/16, .5

ivann1987 [24]

So before I tell you the answer this is a bit of explanation:)

To make it easier change the fraction into decimals!

3/8 = .375

5/16 =.3125

7/12 = .583

.5 = 0.5

.25 = 0.25

So, according to my calculations I believe it goes like this: 0.25, 0.375, 0.3125, 0.5, .583

Really I am not sure if this is correct but I hope this helps you understand you can order it whatever way you want but make sure you understand the explanation :) have a great day!!

Don's Car Rentals charges a flat rate of $35 per day plus $2 per mile. If the number of miles is represented by m, what is the a

Mumz [18]

Given that, Don's Car Rentals charges a flat rate of $35 per day plus $2 per mile.

The number of miles is represented by m.

For 1 mile the charge is $2. So, for m miles the charges will be 2m.

Since, Don's Car Rentals charges a flat rate of $35 per day .

So, total charge must be the sum of 35 and 2m.

Hence, the algebraic expression representing the overall rate for the day is

35 + 2m.

Hope this helps you.
