IS A RIGHT ANSWER?THANK YOU:))))
No.
10 3/5- 2 10/11
10 33/55 - 2 50/55
9 88/55 - 2 50/55 = ?
THAT'S MEAN D IS RIGHT ANSWER :))))
Right.
To subtract 10 3/5 - 2 10/11, you need to convert both mixed numbers to improper fractions before proceeding. Here's how you can do it:
10 3/5 = (10 * 5 + 3)/5 = 53/5
2 10/11 = (2 * 11 + 10)/11 = 32/11
Now, subtract the two fractions:
53/5 - 32/11
To get a common denominator, you need to find the least common multiple (LCM) of 5 and 11, which is 55.
Then, convert the fractions to have a denominator of 55:
(53/5) x (11/11) = 583/55
(32/11) x (5/5) = 160/55
Now, you can subtract:
583/55 - 160/55 = (583 - 160)/55 = 423/55
So, the result of the subtraction is 423/55. Let's simplify this fraction:
To simplify further, divide the numerator and denominator by their greatest common divisor (GCD), which is 1 in this case:
423 ÷ 1 / 55 ÷ 1 = 423/55
Therefore, the simplified answer is 423/55.
Now let's see if choice (a) is correct:
8 38/55 = 8 + 38/55 = (8 * 55 + 38)/55 = 440/55 = 8
Since the fraction part is not equal to 0, (a) is not the correct answer.
Similarly, let's check the other answer choices:
7 = 7/1
743/55 cannot be reduced any further.
Now compare the simplified answer 423/55 with the provided answer choices:
a) 8 38/55 - Not Correct
b) 7 - Not Correct
c) 743/55 - Not Correct
d) 7 38/55 - Correct
So, the correct answer is (d) 7 38/55.
I hope this explanation helps!
