Margaret [11]

Answer:

The solution is 6\frac{7}{10}.

Step-by-step explanation:

It is given that rule start at 5\frac{1}{2} add 1\frac{1}{5}.

From the given information, we get the expression

5\frac{1}{2}+1\frac{1}{5}

Simplify the complex fraction.

\frac{10+1}{2}+\frac{5+1}{5}

\frac{11}{2}+\frac{6}{5}

Taking LCM, we get

\frac{11\times 5+6\times 2}{2\times 5}

\frac{55+12}{10}

\frac{67}{10}

6\frac{7}{10}

Therefore the he solution is 6\frac{7}{10}.

Keith_Richards [23]
The problem is simply asking as to convert the measurement from the smaller scale to the actual scale. For this, we simply multiply the factor to the smaller measurement. We do as follows:

Length = 1 1/8 x 8 = 9 ft
