Plant B is 6 2/3 inches tall. and C is 4 4/15 inches tall. Complete the sentences and show your reasoning
artcher [175]

Answer:

Plant C is <u>0.64</u> times as tall as Plant B

Plant C is <u>2.4 inches</u> shorter than Plant B

Step-by-step explanation:

Plant B is 6 2/3 inches tall. Plant B is 20/3 inches tall.

Plant C 4 4/15 inches tall. Plant C is 64/15 inches tall.

a.) Plant C is shorter than Plant B = \frac{64}{15} \times \frac{1}{\frac{20}{3} }  = \frac{64}{15} \times\frac{3}{20}  = \frac{16}{25} = 0.64 times.

b.) Plant C is shorter than Plant B by = \frac{20}{3}  - \frac{64}{15}  = \frac{100}{15}  - \frac{64}{15}  = \frac{100 -64}{15}  = \frac{36}{15} = 2\frac{2}{5} = 2.4 inches

x = 71

In short, Your Answer would be 71

Hope this helps!
