Find multiples of 30 and 40:
30: 30, 60, 90, 120, 150
40: 40, 80, 120, 160
The least common multiple is 120, so every 120 minutes they willl both ring.
1 hour = 60 minutes:
120/60 = 2 hours.
The bells ring together every 2 hours.
8 + 2 = 10 am
10 + = 12pm
12 + 2 = 2 pm
The bells will ring together at am, 12 pm and 2 pm.
Question:
Marco plotted the following points on the number line.
Point A: 0.3 Point B: 3/4 Point C: 11/4 Point D: 0.7
Which point did he plot incorrectly?
Answer:
Point D
Step-by-step explanation:
Given

Required
The incorrectly plotted point
Number plotted on a number line increases from left to right. This implies that:

Substitute the values for the given points

Express as fractions

Up till 2.75, the order of the numbers is correct.
However, 0.7 is less than 0.75 and 2.75
So, 0.7 is not placed correctly.
<em>This implies that point D is not correctly placed</em>
Answer:
c. 1
inches
Step-by-step explanation:
Since the paper clip is past the 1, the answer will be 1 and ___.
the mark in the middle of the 1 and 2 is one half (1/2)
the mark in between the 1 and 1/2 is 1/4
the mark between 1/4 and 1/2 is 1/8
there are three (3) 1/8 marks where the paperclip is
3 * 1/8 = 3/8
so your answer is 1 3/8
hope this helps:)
2/3 is the answer. You divide both numbers by 6 and you will get your lowest factor
