Question

One and one fourth multiplied by forty five

Answer 1

You can first make 1 1/4 into a number (1.25) and then multiply that.

1.25 * 45 = 52.25

Next make 52.25 into a fraction --> 52 1/4

Answer 2

1 and 1/4 is 1.25 which is 5/4×45
=(5×45)/4
=225/4
you can use the division algorithm to simplify further but the mixed should do.
