Using appropriate property find ‐3/5 × 3/7 + 4/5 ‐ 3/7 × 1/10

-3/5 × 3/7 + 4/5 – 3/7 × 1/10

(-3) × 3 ÷ 5(7) + 4/5 – 3 × 1 ÷ 7(10)

-9/35 + 4/5 – 3/70

-9/35 – 3/70 + 4/5

-9 × 2/35 × 2 – 3/70 + 4/5

-18 – 3/70 + 4/5

-21/70 + 4/5

-3/10 + 4/5

(-3)(5) + (10)(4) ÷ (10)(5)

-15 + 40/50

25/50 = 1/2

Thus, The answer is 1/2

-TheUnknownScientist 72

the answer is b. 60. each interior angle in 120, so the exterior angle must be 60 in order to add up to 180

step-by-step explanation:

answer: 4 meters

step-by-step explanation: to you understand 2/3 better you can do 1 divided by 3 = . then multiply that by the 2 which is .66666666666666667 then you would do 6 x .66666666666666667 which is 4.      

hope this .
