Cargo Division
Step 1
Slide to estimate
Round the numbers to guess the cargo load. We are calculating: {{ problem.dividend }} ÷ {{ problem.divisor }}
Cargo Amount ({{ problem.dividend }})
{{ estDividend }}
{{ Math.floor(problem.dividend/100)*100 - 200 }}
{{ Math.ceil(problem.dividend/100)*100 + 200 }}
Stations ({{ problem.divisor }})
{{ estDivisor }}
{{ Math.floor(problem.divisor/10)*10 - 20 }}
{{ Math.ceil(problem.divisor/10)*10 + 20 }}
Good estimate! ({{ targetEstDividend }} ÷ {{ targetEstDivisor }} = {{ targetEstDividend / targetEstDivisor }})
Step 2
Drag the digit
How many times does {{ problem.divisor }} go into {{ firstPartDividend }}?
{{ problem.divisor }}
{{ q1 }}
{{ problem.dividend }}
-{{ problem.divisor * q1 }}0
{{ firstRem }}5
{{ n }}
{{ problem.divisor }} × {{ q1 }} = {{ problem.divisor * q1 }}. Brought down the last digit!
Step 3
Tap to multiply
Find how many {{ problem.divisor }}s fit into {{ currentTarget }}.
Target: {{ currentTarget }}
{{ s3Total }}
{{ problem.divisor }}
{{ s3ErrorMsg }}
Correct! {{ problem.divisor }} × {{ q2 }} = {{ problem.divisor * q2 }}. Remainder is {{ problem.remainder }}.
Step 4
Build the check
Verify: Quotient × Divisor + Remainder = Dividend
{{ s4Eq[0] ? s4Eq[0].val : '?' }}
×
{{ s4Eq[1] ? s4Eq[1].val : '?' }}
+
{{ s4Eq[2] ? s4Eq[2].val : '?' }}
=
{{ problem.dividend }}
Mission Complete!
You successfully divided the cargo.
$$ {{ problem.dividend }} \div {{ problem.divisor }} = {{ problem.quotient }} \text{ R } {{ problem.remainder }} $$
