Answer:

Answer:

Step-by-step explanation:

15 = 1*3*5

64 = 1*8*8 = 1*2*2*2*2*2*2

15 and 64 have only "1" that presents in both 15 and 64.

So, GCF of 15 and 64 is 1.

How can you use base ten blocks to find 2.16 divided by 3

Answers

For this question, let's move the decimal number 2 spaces to the right. 2.16-->216You need 21 ten rods and 6 cubes. Why: I wouldn't do 2 hundred flats because 2 isn't divisible by 3.Put the ten rods into 3 equal group, then do the same with the cubes.You should end up with 7 in each group since 21 divided by 3 is 7.You should also end up with 2 cubes in each group.So in one group you have 72. Now move the decimal back to where it came from, 2 spaces to the left. Now you have 0.72.

Final answer:

Using base ten blocks to divide 2.16 by 3 involves representing 2.16 with the blocks, then dividing them into three equal groups. The result is 0.72.

Explanation:

To use base ten blocks to find 2.16 divided by 3, we first represent the number 2.16 using base ten blocks. This can include two 1-blocks, one 1/10-block (which represents 0.1), and six 1/100-blocks (which represent 0.1 each). Then we divide these blocks evenly among three groups, as we're dividing by 3.

Each group would end up with 0.72, as we would distribute the 1-blocks, the 1/10-block, and the 1/100-blocks evenly among the 3 groups. Therefore, 2.16 divided by 3 is 0.72 when using base ten blocks.

What is the arithmetic operator?

Arithmetic operators are four basic mathematical operations in which summation, subtraction, division, and multiplication involve.,

As per the given,

Time is taken to Lisa to cover 200 m in normal = one and a 10 seconds.

Since 1 minute = 60 seconds.

One and 10 seconds = 60 + 10 = 70 seconds.

Time is taken in low hurdles = one and a half minutes.

⇒ 60 + 60/2 = 90 seonds.

Thus, 90 seconds - 70 seconds = 20 seconds.

Hence "Lisa Lilly takes 20 seconds more due to low hurdles".
