4 & 7/8 divided by 1 & 1/6

Mathematics
1 answer:
belka [17]3 years ago
4 0

Answer:

4  \frac{5}{28}

Step-by-step explanation:

4  \frac{7}{8}  \div 1  \frac{1}{6}

Convert the mixed numbers above to improper fractions

=  \frac{39}{8}  \div  \frac{7}{6}

Rule of basic operation states that when dividing fractions, the division sign changes to multiplication sign thus turn the right hand side of the fraction inversely such that 7/6 becomes 6/7.

=  \frac{39}{8}  \times  \frac{6}{7}

=  \frac{39 \times 6}{8 \times 7}

=  \frac{234}{56}

Converting the answer above to mixed number result to:

= 4  \frac{5}{28}

Equality Properties

Step-by-step explanation:

<u>Step 1: Define Equation</u>

7(2x - 5) = 21

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Distribute 7:                   2x - 5 = 3
  2. Isolate <em>x</em> term:                2x = 8
  3. Isolate <em>x</em>:                         x = 4

<u>Step 3: Check</u>

<em>Plug in x into the original equation to verify it's a solution.</em>

  1. Substitute in <em>x</em>:                  7(2(4) - 5) = 21
  2. Multiply:                             7(8 - 5) = 21
  3. Subtract:                            7(3) = 21
  4. Multiply:                             21 = 21

Here we see that 21 does indeed equal 21.

∴ x = 4 is the solution to the equation.
