is toby’s calculation correct? draw a number line to support your answer.

Step-by-step explanation:

The given expression is

We can rewrite the expression as

When we subtract expressions on the left

While Toby's result after solving this is

Therefore, Toby has done a mistake in this step.

will be the answer.

start with a line segment pq that we will copy. mark a point r that will be one endpoint of the new line segment. set the compasses' point on the point p of the line segment to be copied. adjust the compasses' width to the point q. the compasses' width is now equal to the length of the line segment pq.

step-by-step explanation:

.632

step-by-step explanation:

6 * 1/10 = 3/5

3*0.01 = 0.03

3/5 + 0.03 = .63

2*0.002 = .002

.63 + 0.002 = .632
