Adante begins to evaluate the expression 3 1/3 * 5 1/4

goldenfox [79]

For this case we must find the product of two mixed numbers:

$3 \frac {1} {3} = 3 + \frac {1} {3} = \frac {9 + 1} {3} = \frac {10} {3}\\5 \frac {1} {4} = 5 + \frac {1} {4} = \frac {20 + 1} {4} = \frac {21} {4}$

So, we have:

$\frac {10} {3} * \frac {21} {4} = \frac {10 * 21} {3 * 4} = \frac {210} {12} = \frac {105} {6} = \frac {35} {2}$

If we go to a mixed number we have:

$\frac {35} {2} = 17 \frac {1} {2}$

Answer:

$17 \frac {1} {2}$

Which rules has a scale factor of 5 and shifted up and to the left?

serious [3.7K]

Answer:

185 37 = 5 1; the scale factor is 5: 1. So every other linear measure is multiplied times 5. If we have the big right triangle and want to scale it down to make the smaller one, we write this: 37 185 = 1 5
