<u>Pre-Alg</u>
- Order of Operations: BPEMDAS
- Equality Properties
Step-by-step explanation:
<u>Step 1: Define equation</u>
12 = 5/2b
<u>Step 2: Solve for </u><em><u>b</u></em>
- Rewrite: 5/2b = 12
- Divide both sides by 5/2: b = 24/5
<u>Step 3: Check</u>
<em>Plug in b to verify it's a solution.</em>
- Substitute: 12 = 5/2(24/5)
- Multiply: 12 = 12

Let's find the equivalent fractions
A/B ; C/D ⇔ A·D/B·D ; C·B/B·D
Bringing to our problem:
A/B ; C/D ⇔ A·D/B·D ; C·B/B·D
1/3 ; 2/5 ⇔ 1·5/3·5 ; 2·3/3·5 ⇔ 5/15 ; 6/15
Now we can sum/add the equivalent fractions
5/15 + 6/15 = 11/15
11/15 to accomodation and food
15/15 = total
total - (accomodation and food) = other purposes
15/15 - 11/15 = 4/15
So 4/15 its the fraction for other purposes
