Question

Use the following pattern to answer the questions. 24.3, 24, 23.7, 23.4, ___,____. part A. ( what is the rule for the pattern?

Answer 1

Answer

Option B. Subtract 0.3 from each term.

Step-by-step explanation:

If you follow the pattern 24.3-24=0.3

similarly 24-23.7=0.3

23.7-23.4=0.3

Conclusion : We will subtract 0.3 every time in order to get the new number.

Answer 2

Question 1:

For this case we have the following pattern of numbers:

24.3, 24, 23.7, 23.4

It can be seen that subtracting 0.3 from the first number of the pattern gives $24.3-0.3 = 24$

Equally if we subtract 0.3 successively we obtain:

$24-0.3 = 23.7\\\\23.7-0.3 = 23.4\\\\23.4-0.3 = 23.1\\\\23.1-0.3 = 22.8$

Thus, 0.3 must be subtracted from each term and the following numbers of the pattern shall be 23.1 and 22.8

Answer:

subtract 0.3 from each term

The next two numbers of the pattern are 23.1 and 22.8

Question 2:

For this case we have the following operation:

$0.52 + 0.61 = 1.13\\\\1.13> 1$

We note that the sum is greater than 1

The sum of two hundredth decimals does not necessarily have to be greater than 1.

Therefore, the correct option is: the sum is greater than 1 because the sum shades more than one hundredths grid.

Answer:

Option C

Question 3:

For this case we have to:

$a + b + c = 2$

Being a, b, c decimal numbers, one of them was 0.34. Suppose $a = 0.34$

Thus: $0.34 + b + c = 2$

We choose values ​​for b and c, in order to obtain the number 2 as a result of the sum. We can choose infinite values ​​so that equality is fulfilled

If$b = 0.96$ and

$c = 0.7$

we have: $0.34 + 0.96 + 0.7 = 2$

Thus, Holland can add to the sum $b = 0.96$ and $c = 0.7$

Answer:

$b = 0.96\\\\c = 0.7$

Question 4:

For this case we have the following subtraction:

$3.5 - 2.46 = 1.16$

This operation is wrong, subtracting $3.5-2.46$ results in 1.04

Let's explain a model for Maysa:

We have the following expression

$3.5 - 2.46$

Rewriting each number in expanded form we have:

$(3 + 0.5) - (2 + 0.46)$

Using the distributive property we have:

$(3 + 0.5) -2-0.46$

Using the associative property we have:

$(3-2) + (0.5-0.46)$

Performing each operation:

$1 + 0.04 = 1.04$

Anwer:

The subtraction of Maysa is wrong, the correct answer is:

$3.5 - 2.46 = 1.04$
