1 answer:
Answer:
Hence the weekly earnings of Nghiep= $136
Step-by-step explanation:
Let the weekly income of Nghiep be $ x.
As it is given that:
- Nghiep gave his mother half of his weekly earnings i.e. the amount he gave to his mother= $ (x/2).
So now we will be left with= $(x/2).
- Next he then spent half of what was left on a new shirt.
so the amount he spent on his shirt= $ (x/4)
Now he will be left with = $ (x/4).
Now it is given that the amount he had after spending on his shirt and giving to his mother= $ 34
i.e.
Hence, the weekly earnings of Nghiep= $136.

32 × 2 = 68
32 × 3 = 96
32 × 4 = 128
So far we can conclude that the answer to your question lies somewhere between the numbers 3 and 4. To narrow down the answer some more, multiply 32 by 3.5 (a midway point between 3 and 4).
32 × 3.5 = 112
The number 112 tells us that the decimal we are looking for is higher than 3.5. (Because we need to get to 125, not 112.) Let's try some decimals between 3.5 and 4.
32 × 3.7 = 118.4
32 × 3.8 = 121.6
32 × 3.9 = 124.8
32 × 4 = 128
As we narrow down our answer, we can see that the number we are looking for lies between 3.9 and 4 on the number line. Now we need to start testing some decimals between 3.9 and 4.
32 × 3.905 = 124.96
Again, use the number five as a "midway" point to decide if you should use numbers that are higher or lower than 3.905. In this case, we need to use numbers higher than 3.905.
32 × 3.906 = 124.992
32 × 3.907 = 125.024
We are getting even closer to our number now that we know the decimal is somewhere between 3.906 and 3.907.
32 × 3.9065 = 125.008
With our midway point we can see that our number lies between 3.906 and 3.9065. Let's try a quarter point to see where our number lies from there.
32 × 3.90625 = 125
And BINGO! We have found the answer to the question. To be rephrased, our answer can be put like this:
= 3.90625
