Palo ya motlakase e le nngwe e tlhoka megala e le mekae go fetisetsa motlakase kwa motseng, fa go itsege gore palokae nngwe le nngwe e tlhoka megala e meraro, mme megala yotlhe e e tlhokiwang ke 45?

If a classroom has 3 times as many girls as they do boys, and 1/10 as many nongendered children as they do boys, and the classroom has 30 boys.  How many total children does it have?
Palo ya megala le dipalo tsotlhe ke 1+3=<<1+3=4>>4
Karolo ya megala e e tlhokiwang ke <<3/4=3/4>>3/4
Fa 3/4 e emela megala e le 45, go raya gore palo yotlhe ya megala le dipalo ke 4/4*45*4/3=60
Fa palo yotlhe ya megala le dipalo e le 60 mme megala e le 45, go raya gore palo ya dipalo ke 60-45=<<60-45=15>>15

The classroom has 3 * 30 boys = <<3*30=90>>90 girls.
The classroom has 1/10 nongendered children so 10/100 * 30 boys = <<10/100*30=3>>3 nongendered children.
In total the classroom has 90 + 30 + 3 = <<90+30+3=123>>123 students.
