Mathilda is determined to pay back the money she owes a friend so she decides to pay an initial installment of $125. If she still has 75% left to pay, how much did she owe originally?
Матилда қарор кардааст, ки пулеро, ки ба дӯсти худ қарздор аст, баргардонад, бинобар ин ӯ қарор мекунад, ки аввалин қимати $125 пардохт кунад. Агар ӯ ҳанӯз 75% боқӣ монда бошад, пас ӯ дар асл чанд пул қарздор буд?
How much did she originally pay? ** Percentage means per 100, so if she still owes 75%, she must have paid 100% - 75% = 25% of the original amount.
How much did she originally pay? ** 25% of the original amount = (25/100)*original amount = $125
How much did she originally pay? ** Multiplying both sides by (100/25) gives: original amount = (100/25)*$125 = $<<(100/25)*125=500>>500

How much did she originally pay? ** Фоиз маънои 100-ро дорад, пас агар ӯ ҳанӯз 75% қарздор бошад, ӯ бояд 100% - 75% = 25% аз миқдори аслӣ пардохт кардааст.
How much did she originally pay? ** 25% аз миқдори аслӣ = (25/100)*миқдори аслӣ = $125
How much did she originally pay? ** Агар ҳар ду тарафро бо (100/25) зарб кунем, ба даст меорем: миқдори аслӣ = (100/25)*$125 = $<<(100/25)*125=500>>500
