The missing expression should be for Step 3 is [(25 + 3)/0.5] - 16.4 ÷ 4 and the missing expression should be for Step 6 is 56 - 4.1
<h3>Part A: Explain what the missing expression should be for Step 3</h3>
To do this, we make use of the expression in step 2
The expression in step 2 is
[(5^2 + 3)/0.5] - 16.4 ÷ 4
The next step at this stage is to evaluate the expression 5^2
So, we have:
[(25 + 3)/0.5] - 16.4 ÷ 4
Hence, the missing expression should be for Step 3 is [(25 + 3)/0.5] - 16.4 ÷ 4
<h3>Part B: Explain what the missing expression should be for Step 6.</h3>
To do this, we make use of the expression in step 5
The expression in step 5 is
56 - 16.4 ÷ 4
The next step at this stage is to evaluate the expression 16.4 ÷ 4
So, we have:
56 - 4.1
Hence, the missing expression should be for Step 6 is 56 - 4.1

Bike > ________300km_________< Van
20km/h 80km/h
In one hour, the bike will have moved 20km and the van would have moved 80km.
The distance between them was 300km. But the bike moved 20km and the van moved 80km, since its been one hour. Which means the distance between them is less.
300km-(20km+80km) = 200km
So now the distance between them is 200km.
Now another hour passes. The distance between them was 200km. But the bike moved 20km and the van moved 80km, since its been one hour. Which means the distance between them is less.
200km-(20km+80km) = 100km
So now the distance between them is 100km
Now another hour passes. The distance between them was 100km. But the bike moved 20km and the van moved 80km, since its been one hour. Which means the distance between them is less.
100km-(20km+80km) = 0km
So now the distance between them is 0km, which means they have met. If we count, it took them 3 hours.
:
Step 1)
Add both speeds. 20km+80km=100km
Step 2)
Total distance between them = 300km
So do 300km/100km = 3hours.

<h3><u>AnswEr</u><u> </u><u>:</u></h3>
The 2 unknown numbers are 4 and 5 .
<h3><u>Expla</u><u>nation</u><u> </u><u>:</u></h3>
Let the numbers be x and x + 1.
From the given information,






But, as we know -5 is not a natural number,
Hence, x = 4 .
<u>So the 2 unknown numbers are</u><u> </u><u>:</u>
- x + 1 = 4 + 1 = 5 [2nd number]
