Question

(1,75-1 7/8+1/2):9/16+2/3

Answer 1

$(1 \frac{3}{4} - 1 \frac{7}{8} + \frac{1}{2} ) \div \frac{9}{16} + \frac{2}{3} = ( \frac{6 - 7 + 4}{8} ) \div \frac{9}{16} + \frac{2}{3} = \frac{3}{8} \times \frac{16}{9} + \frac{2}{3} = \frac{2}{3} + \frac{2}{3} = \frac{4}{3} = 1 \frac{1}{3}$

Answer 3

Let's solve the given expression step by step:

Step 1: Simplify the first part of the expression (1,75 - 1 7/8 + 1/2) To add or subtract mixed numbers, we first convert them into improper fractions.

1,75 = 1 + 0,75 = 1 + 3/4 = 4/4 + 3/4 = 7/4 1 7/8 = 8/8 + 7/8 = 15/8

Now, subtracting 15/8 from 7/4:

7/4 - 15/8 = (72)/(42) - 15/8 = 14/8 - 15/8 = -1/8

Finally, add 1/2 to the result:

-1/8 + 1/2 = 4/8 + 1/2 = 4/8 + 4/8 = 8/8 = 1

Step 2: Simplify the second part of the expression (9/16 + 2/3) The denominators are different, so we need to find a common denominator.

The least common multiple (LCM) of 16 and 3 is 48.

Now, convert the fractions to have a common denominator of 48:

9/16 = (93)/(163) = 27/48 2/3 = (216)/(316) = 32/48

Now, add the fractions:

27/48 + 32/48 = (27 + 32)/48 = 59/48

Step 3: Divide the results from Step 1 and Step 2:

1 ÷ (59/48) = 1 * (48/59) = 48/59

So, the final result is 48/59.
