Answer: 10

=======================================================

Explanation:

We'll start off converting each mixed number into an improper fraction.

The formula to use is [tex]A \frac{b}{c} = \frac{A*c+b}{c}[/tex]

So,

[tex]A \frac{b}{c} = \frac{A*c+b}{c}\\\\2 \frac{1}{8} = \frac{2*8+1}{8}\\\\2 \frac{1}{8} = \frac{16+1}{8}\\\\2 \frac{1}{8} = \frac{17}{8}\\\\[/tex]

And,

[tex]A \frac{b}{c} = \frac{A*c+b}{c}\\\\2 \frac{2}{3} = \frac{2*3+2}{3}\\\\2 \frac{2}{3} = \frac{6+2}{3}\\\\2 \frac{2}{3} = \frac{8}{3}\\\\[/tex]

So the task of computing [tex]2 \frac{1}{8} \times 2 \frac{2}{3}[/tex] is exactly the same as computing [tex]\frac{17}{8} \times \frac{8}{3}[/tex]

Notice how we have an 8 up top and an 8 down below. Those 8's cancel out and we're left with [tex]\frac{17}{3}[/tex]. That fraction does not reduce any further.

The last step is to convert that improper fraction result to a mixed number.

[tex]\frac{17}{3} = \frac{15+2}{3}\\\\\frac{17}{3} = \frac{15}{3}+\frac{2}{3}\\\\\frac{17}{3} = 5+\frac{2}{3}\\\\\frac{17}{3} = 5 \frac{2}{3}\\\\[/tex]

Or you could note that 17/3 leads to 5 remainder 2. The 5 is the whole part and the 2 forms the numerator of the fractional part 2/3.

The value is in [tex]A \frac{b}{c}[/tex] form where

  • A = 5
  • b = 2
  • c = 3

Therefore, A+b+c = 5+2+3 = 10

Answer:

B. 10

Step-by-step explanation:

2 1/8 * 2 2/3

=  8 * 2 + 1 = 17

2 1/8 = 17/8

= 3 * 2 + 2 = 8

2 2/3 = 8/3

17/8 * 8/3

17 * 8 = 136

3 * 8 = 24

136/24 = 17/3 = 5 2/3

5 + 2 + 3 = 10

so I think B. 10 is the answer
