Question

Ruma had a piece of ribbon she cut the ribbon into four pieces measuring 16/3 cm ,9/4 cm,28/6 cm,and 38/8 cm.find the length of the ribbon​

Answer 1

Step-by-step explanation:

Correct Question :-

Ruma had a piece of ribbon she cut the ribbon into four pieces measuring 16/3 cm ,9/4 cm,28/6 cm,and 38/8 cm.find the total length of the ribbon

Solution :-

let the total length of ribbon be X m

According to the question :-

X =

$\frac{16}{3} + \frac{9}{4} + \frac{28}{6} + \frac{38}{8}$

Take the LCM of (3,4,6,8)

= 24

now add these numbers

$\frac{128 + 54 + 112 + 114}{24} \\ \\ \frac{408}{24} \\ \\ \frac{102}{6} \\ \\ 17m$

therefore the total length of ribbon is 17m

Ruma had a piece of ribbon she cut the ribbon into four pieces measuring 16/3 cm ,9/4 cm,28/6 cm,and 38/8 cm.find the length of the ribbon..?

$\huge\underbrace\mathfrak\color{blue}Solution:-$

•Pieces of ribbon into four pieces measuring 16/3 cm, 9/4 cm, 28/6 cm, 38/8 cm.

• So, the length of the ribbon -->

$\frac{16}{3} + \frac{9}{4} + \frac{28}{6} + \frac{38}{8} \\ - > \frac{16 \times 8 + 9 \times 6 + 28 \times 4 + 38 \times 3}{24} \\ lcm \: \: = > 24 \\ - > \frac{128 + 54 + 112 + 114}{24} \\ - > \frac{408} {24} \\ - > 17cm$

So,the length of the ribbon will be 17 cm..
