Answer 2

\(a,=2m+\dfrac{15}{100}m=2\dfrac{3}{10}m\\ b,=5m+\dfrac{36}{100}m=5\dfrac{18}{50}m\\ c,=1m+\dfrac{75}{100}m=1\dfrac{3}{4}m\\ d,=8m+\dfrac{8}{100}m=8\dfrac{2}{25}m\\ e,=7dm+\dfrac{3}{10}dm=7\dfrac{3}{10}dm\\ f,=30m+\dfrac{7}{100}m=30\dfrac{7}{100}m\)

Answer 3

a) 2m 15 cm = 2m + \(\dfrac{15}{100}\)m = 2\(\dfrac{15}{100}\)m

b) 1m 75cm = 1m + \(\dfrac{75}{100}\)m = 1 \(\dfrac{75}{100}\)m

c) 5m 36cm = 5m + \(\dfrac{36}{100}\)m = 5\(\dfrac{36}{100}\)m

d) 8m 8cm = 8m + \(\dfrac{8}{100}\)m = 8\(\dfrac{8}{100}\)m

e)  7dm 3m = 7m + \(\dfrac{3}{10}\)dm= 7m \(\dfrac{3}{10}\)dm

f) 30m 7m = cái này ko bít
