Step 1: Seperate the mixed numbers from their fractions.
- 5  - \frac{5}{7}  + 8  - 3 -  \frac{2}{7}
Step 2: Add -5 and -3. The sum of that is -8, thus we have an additive inverse. 8 and -8 cancel out, becoming a 0.
- 8 -  \frac{5}{7}  + 8 -  \frac{2}{7}  =    - \frac{5}{7}  -  \frac{2}{7}
\frac{ - 5 - 2}{7}  =  \frac{ - 7}{7}  =  - 1
Therefore, the answer is -1

Suppose you are bending stainless steel wire to make the earring shown below. The
lakkis [162]

Given parameters:

Length of earring hook  = 1.5cm

Length of given wire = 45cm

Dimension of the triangle = 3.2cm, 3.2cm and 2.1cm

Unknown:

Number of earrings that can be made from the wire = ?

To solve this problem, we need to calculate the total length of the earring we want to make.

  Total earring length  = Perimeter of earring + length of earring hook

                                      = 3.2 + 3.2 + 2.1 + 1.5  

                                      = 10cm

Now the length of the wire is 45cm,

  Number of earrings  = \frac{45}{10}  = 4.5 earrings

  But this is not reasonable, therefore, we can only forge 4 complete earrings from the given length with 5cm of wire remaining.

The number of earrings that can be made is 4.
