Answer 1

Answer:

Stan requires $\frac{1}{40}\text{ oz}$ of slime to complete his evil plans.

Step-by-step explanation:

RDW strategy is the read draw and write strategy. After reading the question we have the following information:

Total amount of slime required by Stan = $6\frac{3}{8} = \frac{51}{8}\text{ oz}$

Amount of slime Sinister stole from Molly =  $2\frac{3}{4} = \frac{11}{4}\text{ oz}$

Amount of slime Sinister stole from Ralph =  $2\frac{3}{5} = \frac{13}{5}\text{ oz}$

We have to find the amount of slime required to complete the plan.

It can be written as(Writing Technique):

$\text{Slime required} = \text{Total slime - (Slime stolen from Molly + Slime stolen from Ralph)}\\\\\text{Slime required} = \frac{51}{8}-( \frac{15}{4} +\frac{13}{5} )\\\\\text{Slime required} = \frac{51}{8}-(\frac{75+52}{20})\\\\\text{Slime required} = \frac{1}{40}$

Thus, Stan requires $\frac{1}{40}\text{ oz}$ of slime to complete his evil plans.
