Answer:
I think that it's c are b but it could be wrong
First I need to say that the common multiple is when two or more numbers meet up at the same point like 5 and 3 meeting up at 15. The common denominator works almost exactly the same way. It involve two fractions' denominators meeting up like 1/5 and 1/3 meeting up at ?/15 with ? being what the numerator would be (like 1/5 becoming 3/15 because 5 x 3= 15 and you must do so to the numerator so 1 x 3=3. 3/15). So they are alike in the way that they both involve two or more numbers' multiples meeting up, and the common multiple is basically used to find the common denominator.
Answer: Reporting statements is relatively easy. The most common verb used to report statements is tell.
As a general rule, the changes in the tense of the reported speech depend upon the tense of the reporting verb in the direct speech. Thus when the reporting verb is in the past tense, the tense of the reported verb also changes to past tense.
