4, 7 and 9 are mutually coprime, so you can use the Chinese remainder theorem.
Start with
Taken mod 4, the last two terms vanish and we're left with
We have 
, so we can multiply the first term by 3 to guarantee that we end up with 1 mod 4.
Taken mod 7, the first and last terms vanish and we're left with
which is what we want, so no adjustments needed here.
Taken mod 9, the first two terms vanish and we're left with
so we don't need to make any adjustments here, and we end up with 
.
By the Chinese remainder theorem, we find that any 
such that
is a solution to this system, i.e. 
for any integer 
, the smallest and positive of which is 149.
7/8 * cm/ month * 5 months =
35/8 cm
4 3/8 cm
Answer: 4 3/8 cm
Answer:
Rate = 0.035 per weeks
Step-by-step explanation:
Given that,
An artist has completed 1/14 of a painting in 2 weeks.
We need to find the rate at which she is working. Let the rate is R. It can be calculated by dividing part that is completed and time.
Hence, her rate is 0.035 per weeks.
To estimate an amount to the tenth we have 3 steps to follow: ...
STEP 2: We add the rounded numbers. ...
STEP 1: Round the summands.
STEP 2: Add the rounded numbers.
STEP 3: Look at the total amount of rounding.
We have rounded the two summands down.
