Answer:omg I gotchu I just learned these for the letters for example would be q/1 times 2/7 because if you have one letter or number you ALWAYS put a one under it then u multiply another easy trick don’t butterfly multiply go straight across and example 8/1 (all ways add the one) times 3/4. Ok how to multiply that always go across so it would be 8x3 and 1x4 your answer should be 24/4 and simplify if needed
Step-by-step explanation:
1).
[tex]8 \times \frac{3}{4} [/tex]
[tex] = > \frac{8}{1} \times \frac{3}{4} [/tex]
Cancel 8 and 4 by using 2 table
[tex] = > \frac{4}{1} \times \frac{3}{2} [/tex]
Cancel 4 and 2 by using 2 table
[tex] = > \frac{2}{1} \times \frac{3}{1} [/tex]
Now multiply 2×3
[tex] = > \frac{6}{1} = 6[/tex]

2).
[tex]9 \times \frac{2}{7} [/tex]
[tex] = > \frac{9}{1} \times \frac{2}{7} [/tex]
(Here.. we cant cancel)
So multiply the numbers..
[tex] = > \frac{18}{7} [/tex]

3).
[tex] \frac{1}{4} \times \frac{2}{5} [/tex]
Cancel 2 and 4 by using 2 table
[tex] = > \frac{1}{2} \times \frac{1}{5} [/tex]
Multiply..
[tex] = > \frac{1}{10} [/tex]
▪▪▪▪▪▪▪▪▪▪▪▪▪▪▪▪▪
4).
[tex] \frac{4}{5} \times \frac{1}{3} [/tex]
(Here we cant cancel)
[tex] = > \frac{4}{15} [/tex]
