What is 3 3/8 tons equal to in pounds?
guapka [62]

1 ton is equivalent to 2000 pounds

we have to find how many pounds 3 3/8 tons are equal to

if 1 ton --> 2000 pounds

we can break down the fraction into 3 + 3/8

then 3 tons --> 2000 x 3 = 6000 pounds

3/8 ton ---> 2000 x 3/8 = \frac{3*2000}{8} = \frac{6000}{8} = 750 pounds

after adding 6000 + 750 = 6750 pounds

answer is 6750 pounds

ricardo purchased a bunk bed for his children fora sale price of $276.25. The sale price was 65% of the original price. Calculat
nikklg [1K]

Use the formula S=P-PD

S is sale price, original price is P, and PD is discounted percent,

276.25=P-P(.65), I turned the percent into a decimal.

276.25=P(1-.65)

276.25=P(1-.65)

276.25=P(.35)

Now cross multiply.

\frac{276.26}{.35}=\frac{P(.35)}{.35}\\\\P=\frac{276.26}{.35}=789.31

Hope this helps, now you know the answer and how to do it. Stay healthy and safe and HAVE A BLESSED AND WONDERFUL DAY! :-)
