Answer:
-40/8= -5
Step-by-step explanation:
Multiply the top to get -40 then the bottom to get 8. When you simplify, you get -5.
When you're multiplying fractions, you have to multiply the numerators together (2 & 7) and then the denominators (21 & 40).
2x7=14 and 21x40= 840.
Therefore, the fraction becomes 14/840.
To simplify it, you can divide it by 2, and this gives you 7/420.
Both 7 and 420 are both divisible by 7, this then gives you 1/60.
Therefore, 2/21x 7/40 in the simplest form is 1/60
