Answer:

Martina has 18,000

Step-by-step explanation:

  1. Set up the 4/5 the amount Tamara has as a proportion. 4/5 = x/20000
  2. Then cross multiply
  3. 4 * 20,000 = 80,000
  4. 80,000 = 5x
  5. Divide and get 16,000 (This is 4/5 of what Tamara has)
  6. Set up what Martina has as a proportion. 8/9 = 16,000/x
  7. Cross multiply 8x = 16,000 * 9
  8. 8x = 144,000
  9. Divide by 8
  10. 18,000 :)

A jewelry store has 9/10 of an ounce of gold. They need to split it into 1/6 ounce groups. How many groups can they make?
lesya [120]

the amount of gold present is - 9/10 of an ounce of gold

from this gold they have to split into groups of 1/6 ounce each

so we have to divide 9/10 ounce in to groups of 1/6

for this we have to divide 9/10 by 1/6

\frac{9}{10} / \frac{1}{6}

when dividing fractions we mutiply the first fraction by the reciprocal of the second fraction

reciprocal of 1/6 is - 6/1

\frac{9}{10}*\frac{6}{1} = \frac{54}{10} = 5.4


so the number of groups that can be made is 5 whole groups with 0.4 ounce of gold remaining

the whole number of groups that can be made - 5

The result is -3.

The subtraction is:

4 - 7 = -3
