Step-by-step explanation:

Ok, so if there is no number in front of a variable (the letters), there is always a one. So you multiply them like this:

7 x 1b x 4 x 1a x 2 = 56ba

1c x 5 x 1b x 4 x 1a = 20cba

Since there is only a 1 in front of the variables, you can basically just multiply the numbers without variables and then mutiply that times one. Don't forget to add the variables into the answer.

6 x 1p x 4 x 5 x 1w = 120pw

1t x 2 x 1t x 1s =

Please give me brainliest if I helped!

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !
