Answer:
Step-by-step explanation:
if u add 3 to 27, it's 30! now 30 x 2 is 60!
The standard form will be:
a. 3.15
b. 3.015
<h3>How to calculate the value?</h3>
It should be noted that the question is simply about converting the expanded form to standard form.
This will be:
(3 × 1) + (1 × 0.1) + (5 × 0.01)
= 3 + 0.1 + 0.05
= 3.15
b. (3 × 1) + (1 × 0.01) + (5 × 0.001)
= 3 + 0.01 + 0.005
= 3.015

Answer:
Step-by-step explanation:
Prime numbers are numbers that are divisible by itself and '1'. This means prime numbers are numbers with just two factors while composite numbers are numbers that are divisible by more than two numbers, that is they have more than 2 factors.
Example of prime numbers are 5,7,11 etc. We see that these numbers are only divisible by themselves and by '1' while examples of composite numbers are 10, 15, 20, etc. We clearly see that these numbers have more than 2factors.
Answer:
9/10
Step-by-step explanation:
well use distributive property so it be (3x16)-(3x10) --- > 48-30= 18
2x10= 20 so it be 18/20 reduce---> 9/10
