To solve for x, we need to isolate it. We can start by dividing both sides by 4 and 2 fifths:
x = 12 one-tenth ÷ 4 and 2 fifths
To divide mixed numbers, we need to convert them to improper fractions:
x = (122/10) ÷ (22/5)
We can simplify by multiplying by the reciprocal of the second fraction:
x = (122/10) × (5/22)
x = 55/22
This can be simplified by dividing both the numerator and denominator by their greatest common factor of 11:
x = 5/2
Therefore, the answer is C. 2 and one-half.
wrong answer by the bot
as stated:
(4 2/5)x = 12 1/10
22/5 x = 121/10
x = (121/10)(5/22) = 11/4
to get the correct answer
the bot had 12 1/10 as 122/10
should have been 121/10
