IgorC [24]

Answer:

6 3/8

Step-by-step explanation:

Convert the fractions so that the denominators match.

$3\frac{3}{4} =3\frac{6}{8}$ , then $3\frac{6}{8}=\frac{30}{8}$

$1\frac{1}{8}=\frac{9}{8}$

$2\frac{1}{2}=\frac{3}{2}$ , then $\frac{3}{2}=\frac{12}{8}$

Add up the fractions.

$\frac{30}{8}+\frac{9}{8}+\frac{12}{8} =\frac{51}{8} =6\frac{3}{8}$

Two trains, Train A and Train B, weigh a total of 300 tons. Train A is heavier than Train B. The difference of their weights i

eduard

Answer:

Train A = 214

Train B = 86

Step-by-step explanation:

a + b = 300

a - b = 128

a + b = 300

a = 128 + b

(128 + b) + b = 300

128 + b + b = 300

128 + 2b = 300

2b = 300 - 128

2b = 172

b = 172 ÷ 2

b = 86

a = 128 + b

a = 128 + (86)

a = 214
