B. Alex puts 1/4 1of his money in savings and uses 1/( 2) of the remaining money to pay back her sister. If she has GH¢15 left, how much did she have at first?

GH¢60

Step-by-step explanation:

Alex puts 1/4 1of his money in savings and uses 1/( 2) of the remaining money to pay back her sister. If she has GH¢15 left, how much did she have at first?

Let the Total amount of Alex money = 1

We are told that she has GH¢15 left,

Hence, we find the fraction of the money she has left

1 - (1/4 + 1/2)

1 - 3/4

= 1/4

The fraction of the amount she left = 1/4

Let x represent the total amount of money that Alex had

1/4 × x = GH¢15

x / 4 = GH¢15

Cross Multiply

x = 4 × GH¢15

x = GH¢60

Therefore, Alex had GH¢60 at first

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|
