Is 7:11 = 21:44 equivalent?

Question

I'm in school rn and this is too hard for me! Please someone help me with 7:11 = 21:44.

Answer 1

7/11 does not equal 21/44

7/11 does equal 7(3)/11(3) = 21/33

maybe someone's finger got 4 when they were trying for 3, confusing 44 with 33

a mis-copy of the problem

7:11 -= 7/11

21:44 = 21/44

Ratios are equivalent to fractions

IF 7/11 did equal 21/44

then cross multiply, numerator of one fraction times denominator of the 2nd fraction, set equal to the numerator of the 2nd fraction times the denominator of the 1st fraction:

7x44 = 11x21

308 = 231? Nope, not true. They aren't equal.
