Convert them into fractions
i)-2 3/8 = -19/8
ii)0.75 = 75/100 = 3/4
iv) 1 3/4 = 7/4
Now convert all of them in the form of p/q where q = 8
Therefore
ii)6/8
iv) 14/8
Answer:
The correct unit price is $1.17 per pair of gloves. The error is she used number of dozens so, firstly convert it to number of pairs of gloves then divide.
Step-by-step explanation:
It is given 4 dozen pairs of gloves for $56.16.
So, unit price = Divide the price by number of pairs of gloves.
And 1 dozen =12
So 4 dozen =4*12=48 pairs of gloves
So, to find unit rate divide 56.16 by 48.
Unit price =
So, the error is she didn't convert the dozen to units.
That made mistake in finding unit price.
You just use what you already know. You know that 1 week is equal to 7 days so you just do 1 * 7 = 7 or 1 week. Then 54 * 7 = 378
3(x)-5=x+5
3x=-5+5+x
3x=x
0=x
because 3x=x is basically would make each part into 0 which would end up the same.
