13/15 of her allowance was spent in total.
To solve this, you'd need to find the least common denominator (LCD) so that both fractions have the same number on the bottom. In this case, the first number that you could get with 5 and 3 was 15.
Next, you'd have to multiply the numerator by the same amount as the denominator, so that the fractions are proportionate. So, for 1/5, since we had to multiply 5 by 3 to get 15, we'd multiply 1 by 3 as well, giving us 3/15. Doing the same with 2/3, we'd get 10/15.
Then, you add the two fractions together (10/15 + 3/15 = 13/15).
Now, in any other case, you could probably simplify the fraction after you've solved the problem. If we got 12/15 instead of 13/15, then we could simplify that to 4/5, since both 12 and 15 are divisible by 3. But in this case, this is the simplest form of that fraction.
Hope this helped!!!

The farmer plants 195 rows of beets and has 25 beet plants left over
<h2>Hello!</h2>
The answer is:
It will take 4.5 hours for two bricklayers to lay a total of 3150 bricks.
<h2>Why?</h2>
From the statement, we know that on Monday, bricklayers took 3 hours to lay a total of 4200 bricks.
So, we have that the rate of the four bricklayers is given by the following equation:
Therefore, we have that the rate of the four bricklayers is 1400 bricks per hour, meaning that each bricklayer can lay 350 bricks per hour.
Now, to calculate how many hours it will take to the 2 bricklayers to lay a total of 3150, we need to divide the calculated rate (for bricklayers) by two, since there are only 2 bricklayers working on Tuesday.
So, calculating the time, we have:
Hence, we have that it will take 4.5 hours for two bricklayers to lay a total of 3150 bricks.
Have a nice day!
