Answer:
The first question should be [tex]\frac{12}{7} [/tex] or 1[tex]\frac{5}{7} [/tex]
The second question should be 88/9 or 9[tex]\frac{7}{9} [/tex]
Step-by-step explanation:
The mistake in the first question is that they multiplied both the numerator and the denominator by 3, which was incorrect because 3 is essentially 3/1.
The second question is incorrect because they should've converted the fraction into a mixed number, e.g. 11/3 and 8/3, then multiply to get the product
