What is greater 3 x 1/10 plus 4 x 1/100 plus 8x 1/1000 greater than one and two tenths

Elena L [17]

So, first let's change these numbers into decimal form:
3*0.1 + 4*0.01 + 8*0.001 ? 1.2
Multiply:
0.3 + 0.04 + 0.008 ? 1.2
0.348 < 1.2
One and two tenths is larger.
Hopefully this is what you're asking, as this question is unclear

John earns $25 per hour as a part-time firefighter. If John works 30 hours per week, how much does he earn that week?

Tanzania [10]

Answer: $750

Step-by-step explanation:

So we know that he earns $25 per hour, and we want to know how much he earns if he worked for 30 hours which is a week.

25=1

?=30

then we can cross multiply which is

$\frac{25(30)}{1}$ =750

so the answer is John earns $750 a week.
