Question

10 1/12 + 2 5/36 - 970 / 72​

Answer 1

2 70/72-970/72=2 900/72=14 36/72=14 1/2

Answer 2

Alright, let's tackle this! First, let's convert the mixed numbers into improper fractions:

$10 \frac{1}{12} = \frac{121}{12}$

$2 \frac{5}{36} = \frac{77}{36}$

Now, let's substitute these values into the expression:

$\frac{121}{12} + \frac{77}{36} - \frac{970}{72}$

To add or subtract fractions, we need a common denominator. The least common denominator for 12, 36, and 72 is 72. Now, let's rewrite each fraction with the common denominator:

$\frac{121 \cdot 6}{12 \cdot 6} + \frac{77 \cdot 2}{36 \cdot 2} - \frac{970}{72}$

Simplifying, we get:

$\frac{726}{72} + \frac{154}{72} - \frac{970}{72}$

Now, combine the numerators:

$\frac{726 + 154 - 970}{72}$

Simplify the numerator:

$\frac{-90}{72}$

Now, you can simplify the fraction further. The greatest common divisor of 90 and 72 is 18:

$\frac{-5}{4}$

So, $10 \frac{1}{12} + 2 \frac{5}{36} - \frac{970}{72} = -\frac{5}{4}$.
