4.3 increase 5200 kg in the ratio \( 2: 5 \)

To increase 5,200 kg in the ratio of 2:5, we first add the parts of the ratio, which totals 2 + 5 = 7 parts. Then, we can find the value of one part by dividing 5,200 kg by 7, giving us approximately 742.86 kg for each part. To find the specific increases for the 2 and 5 parts, multiply 742.86 kg by 2 and 5, which gives us approximately 1,485.71 kg and 3,714.29 kg, respectively. Thus, the new total will be the original 5,200 kg plus these increases! If you’re ever in a math jam, remember that ratios can be your best friend! Just break down the problem into smaller parts, and don’t forget to keep your calculations neat. A common mistake is to forget to add the parts of the ratio before dividing, so always check that you’ve accounted for all parts when calculating increases!
