Question

answer and explain plzzzz​

Answer 1

$1. \: = 10 + 5 + \frac{1}{10}$

$lcm \: = 10$

$= \frac{(10 \times 10) + (5 \times10) + (1 \times 1)}{10}$

$= \frac{100 + 50 + 1}{10}$

$= \frac{151}{10}$

$= 15.1$

$2. \: 700 + 50 + 6 + \frac{4}{10} + \frac{7}{100}$

$lcm = 100$

$= \frac{70000 + 5000 + 600 + 40 + 7}{100}$

$= \frac{75647}{100}$

$= 756.47$

$3. \: 3000 + 3 + \frac{3}{100} + \frac{3}{1000}$

$lcm = 1000$

$= \frac{3000000 + 3000 + 30 + 3}{1000}$

$= \frac{3003033}{1000}$

$= 3003.033$

Answer 2

Answer:

1. \: = 10 + 5 + \frac{1}{10}1.=10+5+

lcm \: = 10lcm=10

= \frac{(10 \times 10) + (5 \times10) + (1 \times 1)}{10}=

10

(10×10)+(5×10)+(1×1)

= \frac{100 + 50 + 1}{10}=

10

100+50+1

= \frac{151}{10}=

151

= 15.1=15.1

2. \: 700 + 50 + 6 + \frac{4}{10} + \frac{7}{100}2.700+50+6+
