Step 1: Scale it up
A recipe needs {{s1.baseLemons}} lemons for {{s1.baseWater}} cups of water.
Adjust the slider to find out how much water you need for {{s1.targetLemons}} lemons.
🍋
{{s1.baseLemons * s1.multiplier}} Lemons
=
💧
{{s1.baseWater * s1.multiplier}} Water
x1x2x3x4x5x6
Step 2: Set it up
On a map, {{s2.scaleCm}} cm represents {{s2.scaleKm}} km.
Where is a city that is {{s2.mapCm}} cm away on the map?
{{item.val}} {{item.unit}}
Map Scale
Real Problem
MAP (cm)
{{s2.slots.tl.val}} cm
REAL (km)
{{s2.slots.bl.val}} km
=
{{s2.slots.tr.val}} cm
{{s2.slots.br.val}} km
Match the units (cm on top, km on bottom)!
Step 3: Cross Multiply
To solve, we multiply across the diagonals.
Tap two numbers diagonally across from each other to multiply them.
Equation will appear here...
{{s3.a}} × {{s3.c}}
? × ?
=
{{s3.b}}x
?x
Final Step: Solve it
If {{s4.n1}} tickets cost ${{s4.cost1}}, how much do {{s4.n2}} tickets cost?
${{s4.cost1}}
{{s4.n1}} tix
=
$ x
{{s4.n2}} tix
{{s4.n1}}x = {{s4.cost1 * s4.n2}}
$
{{s4.input || '_'}}
