1 7/10 + 2 3/8
1 28/40 + 2 15/40 = 3 43/40 = 4 3/40
1 28/40 + 2 15/40 = 3 43/40 = 4 3/40
Given that Reilly used 1 and 7/10 tubes of paint for the model and 2 and 3/8 tubes of paint for the art project, we'll first add the whole numbers together:
1 + 2 = 3
Now, let's add the fractions:
7/10 + 3/8
To add fractions with different denominators, we first need to find a common denominator. In this case, the least common multiple (LCM) of 10 and 8 is 40.
Next, we'll convert the fractions so they have the same denominator:
(7/10) * (4/4) = 28/40
(3/8) * (5/5) = 15/40
Now that both fractions have the same denominator, we can add them:
28/40 + 15/40 = 43/40
Since we need the answer in terms of whole numbers and proper fractions, we can simplify 43/40.
Divide the numerator (43) by the denominator (40):
43 รท 40 = 1 with a remainder of 3
So, the simplified form of 43/40 is 1 and 3/40.
Now, we can add the whole numbers (3) and the fraction (1 and 3/40):
3 + 1 and 3/40 = 4 and 3/40
Therefore, Reilly used a total of 4 and 3/40 tubes of paint.
